Struct FragmentRef 

pub struct FragmentRef {
    pub file: usize,
    pub unit: usize,
    pub start_byte: usize,
    pub end_byte: usize,
    pub extent: u32,
    pub run: Option<StatementRun>,
}

One occurrence of a hashed fragment (a statement window or a subtree) at a source location. file indexes the slice given to generate; unit indexes that file’s FileFeatures::units.

Fields

file: usize

Index of the file in the input slice.

unit: usize

Index of the enclosing unit in the file’s units.

start_byte: usize

Anchor: first byte the fragment covers.

end_byte: usize

Anchor: one past the last byte the fragment covers.

extent: u32

Kind-specific size: window length or subtree node count.

run: Option<StatementRun>

The statement run this fragment covers, for a statement window. None for a subtree, which is a tree region rather than a run of siblings.

Trait Implementations

impl PartialOrd for FragmentRef

fn partial_cmp(&self, other: &FragmentRef) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.
