Enum Platform

pub enum Platform {
    Name(String),
    Cfg(CfgExpr),
}

Platform definition.

Variants

Name(String)

A named platform, like x86_64-apple-darwin.

Cfg(CfgExpr)

A cfg expression, like cfg(windows).

Implementations

impl Platform

pub fn matches(&self, name: &str, cfg: &[Cfg]) -> bool

Returns whether the Platform matches the given target and cfg.

The named target and cfg values should be obtained from rustc.

pub(crate) fn validate_named_platform(name: &str) -> Result<(), ParseError>

pub fn check_cfg_attributes(&self, warnings: &mut Vec<String>)

Trait Implementations

impl Clone for Platform

fn clone(&self) -> Platform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Platform

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Platform

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Platform

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

Formats the value using the given formatter.

impl FromStr for Platform

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Platform, ParseError>

Parses a string s to return a value of this type.

impl Hash for Platform

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Platform

fn cmp(&self, other: &Platform) -> 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 Platform

fn eq(&self, other: &Platform) -> 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 Platform

fn partial_cmp(&self, other: &Platform) -> 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 Serialize for Platform

fn serialize<S>(&self, s: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Platform

impl StructuralPartialEq for Platform

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.
