Enum Definition

pub enum Definition {
    Path(PathBuf),
    Environment(String),
    Cli(Option<PathBuf>),
}

Location where a config value is defined.

Variants

Path(PathBuf)

Defined in a .cargo/config, includes the path to the file.

Environment(String)

Defined in an environment variable, includes the environment key.

Cli(Option<PathBuf>)

Passed in on the command line. A path is attached when the config value is a path to a config file.

Implementations

impl Definition

pub fn root<'a>(&'a self, gctx: &'a GlobalContext) -> &'a Path

Root directory where this is defined.

If from a file, it is the directory above .cargo/config. CLI and env are the current working directory.

pub fn is_higher_priority(&self, other: &Definition) -> bool

Returns true if self is a higher priority to other.

CLI is preferred over environment, which is preferred over files.

Trait Implementations

impl Clone for Definition

fn clone(&self) -> Definition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Definition

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Definition

fn deserialize<D>(deserializer: D) -> Result<Definition, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Definition

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

Formats the value using the given formatter.

impl Ord for Definition

fn cmp(&self, other: &Definition) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Definition

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Definition

fn partial_cmp(&self, other: &Definition) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Eq for Definition

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.
