Struct target_tuples::Target

pub struct Target { /* fields omitted */ }

The representation of a target tuple.

A Target Tuple is of the form arch-vendor-system, where system can be either os-env or simply either os or env (the latter is used in the case of a freestanding target).

There are two types of target tuple: canonical and exact. This type can be used to represent both.

The core::fmt::Display implementation will display the canonical tuple; the function Self::get_name extracts the exact form that was parsed. In any case, if any field, other than vendor, is unknown, or the form is not the one above, the core::str::FromStr implementation will yield an UnknownError.

Implementations

impl Target

pub fn get_name(&self) -> &str

Gets the exact name of the target tuple.

pub fn get_arch_name(&self) -> &str

Returns the architecture name

pub fn get_vendor_name(&self) -> &str

pub fn parse(s: &str) -> Self

Parses a target tuple of the form arch-vendor-system (where system is either os-env, os, or env). If a field is not known, it is left as unknown, and the original value will be available through the exact name.

Panics if s is not of the above form

pub fn get_operating_system(&self) -> OS

Gets the value of the os field, or unknown if the os was omitted

pub fn get_environment(&self) -> Environment

Gets the value of the env field, or unknown if the environment was omitted

pub fn from_components(
    arch: Architecture,
    vendor: Vendor,
    os: Option<OS>,
    env: Option<Environment>,
    objfmt: Option<ObjectFormat>
) -> Self

Constructs a target tuple in canonical form from the specified components.

pub fn get_object_format(&self) -> ObjectFormat

Gets the object format, either from the end of the env field, or the default for the target

pub fn get_arch(&self) -> Architecture

Gets the value of the Architecture field

pub fn get_vendor(&self) -> Vendor

Gets the value of the vendor field.
