Struct FunctionCoverage 

pub struct FunctionCoverage {
    pub function_name: String,
    pub ranges: Vec<CoverageRange>,
    pub is_block_coverage: bool,
}

V8 per-function coverage. Each function carries one or more CoverageRanges — block-level for instrumented coverage, function-level for --coverage=best-effort.

Fields

function_name: String

Source-as-written function name. Empty for the module-level wrapper and anonymous functions.

ranges: Vec<CoverageRange>

Coverage ranges, byte-offsets relative to the script’s source text.

is_block_coverage: bool

True when V8 emitted block-level data for this function (instrumented coverage). False when only the outer function range is reliable (best-effort / runtime coverage).
