Struct rustc_session::config::OutputTypes

pub struct OutputTypes(BTreeMap<OutputType, Option<PathBuf>>);

Use tree-based collections to cheaply get a deterministic Hash implementation. Do not switch BTreeMap out for an unsorted container type! That would break dependency tracking for command-line arguments. Also only hash keys, since tracking should only depend on the output types, not the paths they’re written to.

Implementations

impl OutputTypes

pub fn new(entries: &[(OutputType, Option<PathBuf>)]) -> OutputTypes

pub fn get(&self, key: &OutputType) -> Option<&Option<PathBuf>>

pub fn contains_key(&self, key: &OutputType) -> bool

pub fn values(&self) -> BTreeMapValuesIter<'_, OutputType, Option<PathBuf>>

pub fn len(&self) -> usize

pub fn should_codegen(&self) -> bool

Returns true if any of the output types require codegen or linking.

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.
