Struct TokenSpan 

pub struct TokenSpan {
    pub start: usize,
    pub len: usize,
}

Byte-offset span of a token (or tokenizer error) into the original source string. Spans are byte offsets, not char indices; UpdateExpression and ProjectionExpression callers slice the original source via &source[span.start..span.start + span.len] to build the AWS-style near: "..." window in error messages.

Fields

start: usize

len: usize

Implementations

impl TokenSpan

pub fn new(start: usize, len: usize) -> Self

pub fn end(self) -> usize

Trait Implementations

impl Clone for TokenSpan

fn clone(&self) -> TokenSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TokenSpan

impl Debug for TokenSpan

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

Formats the value using the given formatter.

impl Eq for TokenSpan

impl PartialEq for TokenSpan

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