clippy_utils::msrvs

Struct Msrv

Source 
pub struct Msrv(Option<RustcVersion>);
Expand description

Tracks the current MSRV from clippy.toml, Cargo.toml or set via #[clippy::msrv] in late lint passes, use MsrvStack for early passes

Implementations§

Source§

impl Msrv

Source

pub fn current(self, cx: &LateContext<'_>) -> Option<RustcVersion>

Returns the MSRV at the current node

If the crate being linted uses an #[clippy::msrv] attribute this will search the parent nodes for that attribute, prefer to run this check after cheaper pattern matching operations

Source

pub fn meets(self, cx: &LateContext<'_>, required: RustcVersion) -> bool

Checks if a required version from this module is met at the current node

If the crate being linted uses an #[clippy::msrv] attribute this will search the parent nodes for that attribute, prefer to run this check after cheaper pattern matching operations

Source

pub fn read_cargo(&mut self, sess: &Session)
