Struct glsl_lang::ast::NodeSpan

pub struct NodeSpan {
    pub source_id: usize,
    pub start: usize,
    pub end: usize,
}

Span information for a node, constructed from a nom_locate::LocatedSpan

Fields

source_id: usize

The index of this span into the list of parsed units. This is used to identify which source string this span refers to when combining multiple ASTs

start: usize

Start of the node in the input slice

end: usize

End of the node in the input slice

Implementations

impl NodeSpan

pub fn new_start(source_id: usize) -> NodeSpan

Return a 0-length span located at the start of the given source

This may be used in span range queries.

pub fn new_end(source_id: usize, length: usize) -> NodeSpan

Return a 0-length span located at the end of the given source (as indicated by the offset)

This may be used in span range queries.

pub fn to_end_location(&self) -> NodeSpan

Return a 0-length span located at the end point of this span.

This may be used in span range queries. Note that the line and column information will not be accurate.

pub fn length(&self) -> usize

Return the length of this span

Trait Implementations

impl Ord for NodeSpan

pub fn cmp(&self, other: &NodeSpan) -> Ordering

This method returns an Ordering between self and other.

#[must_use]pub fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]pub fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]pub fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<NodeSpan> for NodeSpan

pub fn eq(&self, other: &NodeSpan) -> bool

This method tests for self and other values to be equal, and is used by ==.

pub fn ne(&self, other: &NodeSpan) -> bool

This method tests for !=.

impl PartialOrd<NodeSpan> for NodeSpan

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

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

#[must_use]pub fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]pub fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]pub fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]pub fn ge(&self, other: &Rhs) -> bool
