Implementations

impl Cfg

pub(crate) fn render_short_html(&self) -> String

Renders the configuration for human display, as a short HTML description.

fn render_long_inner(&self, format: Format) -> String

pub(crate) fn render_long_html(&self) -> String

Renders the configuration for long display, as a long HTML description.

pub(crate) fn render_long_plain(&self) -> String

Renders the configuration for long display, as a long plain text description.

fn should_append_only_to_description(&self) -> bool

fn should_use_with_in_description(&self) -> bool

pub(crate) fn simplify_with(&self, assume: &Self) -> Option<Self>

Attempt to simplify this cfg by assuming that assume is already known to be true, will return None if simplification managed to completely eliminate any requirements from this Cfg.

See tests::test_simplify_with for examples.

pub(crate) fn sort_for_rendering(&mut self)

Recursively sorts the configuration tree to ensure deterministic rendering.

Sorting groups predicates logically: Targets first, then Target Features, then Crate Features, and finally nested Any/All/Not groupings. Within each group, a fallback alphabetical sort is applied.

fn omit_preposition(&self) -> bool

pub(crate) fn inner(&self) -> &CfgEntry

fn not(self) -> Cfg

Performs the unary ! operation.

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.
