Struct MatchingGroup

pub struct MatchingGroup {
    pub op: MatchingGroupOp,
    pub labels: Vec<String>,
    pub span: Option<Span>,
}

A matching clause’s nested grouping clause

Fields

op: MatchingGroupOp

The matching group’s operator type (left or right)

labels: Vec<String>

A list of labels to copy to the opposite side of the group operator, i.e. group_left(foo) copies the label foo from the right hand side

span: Option<Span>

Implementations

impl MatchingGroup

pub fn new(op: MatchingGroupOp) -> Self

pub fn left() -> Self

Creates a new MatchingGroup with the Left op

pub fn right() -> Self

Creates a new MatchingGroup with the Right op

pub fn op(self, op: MatchingGroupOp) -> Self

Replaces this Matching’s operator

pub fn label<S: Into<String>>(self, label: S) -> Self

Adds a label key to this MatchingGroup

pub fn labels(self, labels: &[&str]) -> Self

Replaces this MatchingGroup’s labels with the given set

pub fn clear_labels(self) -> Self

Clears this MatchingGroup’s set of labels

pub fn span<S: Into<Span>>(self, span: S) -> Self

Trait Implementations

impl Clone for MatchingGroup

fn clone(&self) -> MatchingGroup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MatchingGroup

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

Formats the value using the given formatter.

impl Display for MatchingGroup

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

Formats the value using the given formatter.

impl PartialEq for MatchingGroup

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