Struct cargo::util::toml_mut::dependency::Dependency

#[non_exhaustive]
pub struct Dependency {
    pub name: String,
    pub optional: Option<bool>,
    pub public: Option<bool>,
    pub features: Option<IndexSet<String>>,
    pub default_features: Option<bool>,
    pub inherited_features: Option<IndexSet<String>>,
    pub source: Option<Source>,
    pub registry: Option<String>,
    pub rename: Option<String>,
}

A dependency handled by Cargo.

None means the field will be blank in TOML.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

The name of the dependency (as it is set in its Cargo.toml and known to crates.io).

optional: Option<bool>

Whether the dependency is opted-in with a feature flag.

public: Option<bool>

Whether the dependency is marked as public.

features: Option<IndexSet<String>>

List of features to add (or None to keep features unchanged).

default_features: Option<bool>

Whether default features are enabled.

inherited_features: Option<IndexSet<String>>

List of features inherited from a workspace dependency.

source: Option<Source>

Where the dependency comes from.

registry: Option<String>

Non-default registry.

rename: Option<String>

If the dependency is renamed, this is the new name for the dependency as a string. None if it is not renamed.

Implementations

impl Dependency

pub fn new(name: &str) -> Self

Create a new dependency with a name.

pub fn set_source(self, source: impl Into<Source>) -> Self

Set dependency to a given version.

pub fn clear_version(self) -> Self

Remove the existing version requirement.

pub fn set_optional(self, opt: bool) -> Self

Set whether the dependency is optional.

pub fn set_features(self, features: IndexSet<String>) -> Self

Set features as an array of string (does some basic parsing).

pub fn extend_features(self, features: impl IntoIterator<Item = String>) -> Self

Set features as an array of string (does some basic parsing).

pub fn set_default_features(self, default_features: bool) -> Self

Set the value of default-features for the dependency.

pub fn set_rename(self, rename: &str) -> Self

Set the alias for the dependency.

pub fn set_registry(self, registry: impl Into<String>) -> Self

Set the value of registry for the dependency.

pub fn set_inherited_features(self, features: IndexSet<String>) -> Self

Set features as an array of string (does some basic parsing).

pub fn source(&self) -> Option<&Source>

Get the dependency source.

pub fn version(&self) -> Option<&str>

Get version of dependency.

pub fn registry(&self) -> Option<&str>

Get registry of the dependency.

pub fn rename(&self) -> Option<&str>

Get the alias for the dependency (if any).

pub fn default_features(&self) -> Option<bool>

Whether default features are activated.

pub fn optional(&self) -> Option<bool>

Get whether the dep is optional.

pub fn public(&self) -> Option<bool>

Get whether the dep is public.

pub fn source_id( &self, gctx: &GlobalContext ) -> CargoResult<MaybeWorkspace<SourceId>>

Get the SourceID for this dependency.

pub fn query( &self, gctx: &GlobalContext ) -> CargoResult<MaybeWorkspace<Dependency>>

Query to find this dependency.

impl Dependency

pub fn from_toml(crate_root: &Path, key: &str, item: &Item) -> CargoResult<Self>

Create a dependency from a TOML table entry.

pub fn toml_key(&self) -> &str

Get the dependency name as defined in the manifest, that is, either the alias (rename field if Some), or the official package name (name field).

pub fn to_toml(&self, crate_root: &Path) -> Item

Convert dependency to TOML.

Returns a tuple with the dependency’s name and either the version as a String or the path/git repository as an InlineTable. (If the dependency is set as optional or default-features is set to false, an InlineTable is returned in any case.)

Panic

Panics if the path is relative

pub fn update_toml<'k>( &self, crate_root: &Path, key: &mut KeyMut<'k>, item: &mut Item )

Modify existing entry to match this dependency.

Trait Implementations

impl Clone for Dependency

fn clone(&self) -> Dependency

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Dependency

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Dependency

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'s> From<&'s Summary> for Dependency

fn from(other: &'s Summary) -> Self

Converts to this type from the input type.

impl From<Summary> for Dependency

fn from(other: Summary) -> Self

Converts to this type from the input type.

impl PartialEq for Dependency

fn eq(&self, other: &Dependency) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Eq for Dependency

impl StructuralPartialEq for Dependency

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
