Struct RustCoverage 

pub struct RustCoverage {
    pub regions: Option<u8>,
    pub lines: u8,
    pub functions: Option<u8>,
    pub branch: Option<u8>,
}

[rust].coverage. A partial override — #[serde(default)] fills any missing field from RustCoverage::default (lines = 100, everything else None), so a table that sets only regions keeps lines = 100 (#216); deny_unknown_fields still rejects a typo’d key. Three opt-in floors sit alongside lines (#267): regions (a Rust-only sub-line metric), functions (the export’s functions total, stable toolchain), and branch (adds --branch to the run, which instruments only on a nightly toolchain).

Fields

regions: Option<u8>

lines: u8

functions: Option<u8>

branch: Option<u8>

Trait Implementations

impl Clone for RustCoverage

fn clone(&self) -> RustCoverage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RustCoverage

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

Formats the value using the given formatter.

impl Default for RustCoverage

The default Rust floor used when coverage isn’t configured (#206): lines = 100, matching Python/TypeScript’s line-level 100. The other metrics are opt-in (None unless a config sets them): regions is a Rust-only sub-line metric harsher than lines, functions keeps the default line-shaped like Python’s, and branch requires a nightly toolchain (#267) — so the zero-config floor is lines only. As with Python/TypeScript, “100” means “100% of what you didn’t explicitly exempt” — the rule honors reason-required [[rust.exempt]] entries. A config [rust].coverage table lowers the line floor or adds the opt-in floors.

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RustCoverage

where RustCoverage: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for RustCoverage

impl PartialEq for RustCoverage

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