pub struct Sysroot { /* private fields */ }

Implementations

impl Sysroot

pub const fn empty() -> Sysroot

pub fn root(&self) -> Option<&AbsPath>

Returns sysroot “root” directory, where bin/, etc/, lib/, libexec/ subfolder live, like: $HOME/.rustup/toolchains/nightly-2022-07-23-x86_64-unknown-linux-gnu

pub fn src_root(&self) -> Option<&AbsPath>

Returns the sysroot “source” directory, where stdlib sources are located, like: $HOME/.rustup/toolchains/nightly-2022-07-23-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library

pub fn is_empty(&self) -> bool

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

pub fn num_packages(&self) -> usize

impl Sysroot

pub fn discover( dir: &AbsPath, extra_env: &FxHashMap<String, String>, sysroot_query_metadata: SysrootQueryMetadata, ) -> Sysroot

Attempts to discover the toolchain’s sysroot from the given dir.

pub fn discover_with_src_override( current_dir: &AbsPath, extra_env: &FxHashMap<String, String>, sysroot_src_dir: AbsPathBuf, sysroot_query_metadata: SysrootQueryMetadata, ) -> Sysroot

pub fn discover_sysroot_src_dir( sysroot_dir: AbsPathBuf, sysroot_query_metadata: SysrootQueryMetadata, ) -> Sysroot

pub fn discover_rustc_src(&self) -> Option<ManifestPath>

pub fn tool(&self, tool: Tool) -> Command

Returns a command to run a tool preferring the cargo proxies if the sysroot exists.

pub fn discover_proc_macro_srv(&self) -> Result<AbsPathBuf>

pub fn load( sysroot_dir: Option<AbsPathBuf>, sysroot_src_dir: Option<AbsPathBuf>, sysroot_query_metadata: SysrootQueryMetadata, ) -> Sysroot

Trait Implementations

impl Clone for Sysroot

fn clone(&self) -> Sysroot

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sysroot

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

Formats the value using the given formatter.

impl PartialEq for Sysroot

fn eq(&self, other: &Sysroot) -> 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.
