Struct LibC

pub struct LibC {
    pub family: String,
    pub version: Version,
}

LibC virtual package description

Fields

family: String

The family of LibC. This could be glibc for instance.

version: Version

The version of the libc distribution.

Implementations

impl LibC

pub fn current() -> Result<Option<Self>, DetectLibCError>

Returns the LibC family and version of the current platform.

Returns an error if determining the LibC family and version resulted in an error. Returns None if the current platform does not have an available version of LibC.

Trait Implementations

impl Clone for LibC

fn clone(&self) -> LibC

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LibC

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LibC

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LibC

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

Formats the value using the given formatter.

impl EnvOverride for LibC

const DEFAULT_ENV_NAME: &'static str = "CONDA_OVERRIDE_GLIBC"

Default name of the environment variable that overrides the virtual package.

fn parse_version(env_var_value: &str) -> Result<Self, ParseVersionError>

Parse env_var_value

fn detect_from_host() -> Result<Option<Self>, DetectVirtualPackageError>

Detect the virtual package for the current system. This method is here so that <Self as EnvOverride>::current always returns the same error type. current may return different types of errors depending on the virtual package. This one always returns DetectVirtualPackageError.

fn parse_version_opt( value: &str, ) -> Result<Option<Self>, DetectVirtualPackageError>

Helper to convert the output of parse_version and handling empty strings.

fn from_env_var_name_or<F>( env_var_name: &str, fallback: F, ) -> Result<Option<Self>, DetectVirtualPackageError>

where F: FnOnce() -> Result<Option<Self>, DetectVirtualPackageError>,

Read the environment variable and if it exists, try to parse it with EnvOverride::parse_version If the output is:

fn detect_with_fallback<F>( ov: &Override, fallback: F, ) -> Result<Option<Self>, DetectVirtualPackageError>

where F: FnOnce() -> Result<Option<Self>, DetectVirtualPackageError>,

Apply the override to the current virtual package. If the override is None then use the fallback

fn detect( ov: Option<&Override>, ) -> Result<Option<Self>, DetectVirtualPackageError>

Shortcut for Self::detect_with_fallback with Self::detect_from_host as fallback

impl From<LibC> for GenericVirtualPackage

fn from(libc: LibC) -> Self

Converts to this type from the input type.

impl From<LibC> for VirtualPackage

fn from(libc: LibC) -> Self

Converts to this type from the input type.

impl Hash for LibC

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 PartialEq for LibC

fn eq(&self, other: &LibC) -> 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 Eq for LibC
