Struct PreludeSegment 

pub struct PreludeSegment {
    pub out_start: usize,
    pub len: usize,
    pub user_start: Option<usize>,
}

One run of apply_prelude’s output tied back to where it came from: user_start is the byte offset of an untouched run of the caller’s own text, None marks spliced stdlib text. Downstream span translation (deep check) inverts the prelude edit exactly through these runs.

Fields

out_start: usize

len: usize

user_start: Option<usize>

Trait Implementations

impl Clone for PreludeSegment

fn clone(&self) -> PreludeSegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PreludeSegment

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

Formats the value using the given formatter.

impl PartialEq for PreludeSegment

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