Struct ExpressionIndex

#[repr(transparent)]
pub struct ExpressionIndex(pub c_uint);

Reference to the source expression that produced a match result or error.

This is provided to match results such as Match as well as errors like CompileError, although note that its value should be interpreted differently when received as part of a compile error.

Tuple Fields

0: c_uint

This corresponds to the value of an ExprId argument provided during expression set compilation using e.g. ExpressionSet::with_ids().

This value will be 0 if only a single expression was compiled or if no expression ids were provided.

Trait Implementations

impl Clone for ExpressionIndex

fn clone(&self) -> ExpressionIndex

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionIndex

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

Formats the value using the given formatter.

impl Display for ExpressionIndex

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

Formats the value using the given formatter.

impl From<ExpressionIndex> for c_uint

fn from(x: ExpressionIndex) -> Self

Converts to this type from the input type.

impl From<u32> for ExpressionIndex

fn from(x: c_uint) -> Self

Converts to this type from the input type.

impl Hash for ExpressionIndex

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ExpressionIndex

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ExpressionIndex

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

impl PartialOrd for ExpressionIndex

fn partial_cmp(&self, other: &ExpressionIndex) -> 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.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
