Struct Matching

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

An operator matching clause

Fields

op: MatchingOp

labels: Vec<String>

A list of labels to which the operator is applied

group: Option<MatchingGroup>

An optional grouping clause for many-to-one and one-to-many vector matches

span: Option<Span>

Implementations

impl Matching

pub fn new(op: MatchingOp) -> Self

pub fn on() -> Self

Creates a Matching cause with the On operator

pub fn ignoring() -> Self

Creates a Matching clause using the Ignoring operator

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

Replaces this Matching’s operator

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

Adds a label key to this Matching

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

Replaces this Matching’s labels with the given set

pub fn clear_labels(self) -> Self

Clears this Matching’s set of labels

pub fn group(self, group: MatchingGroup) -> Self

Sets or replaces this Matching’s group clause

pub fn clear_group(self) -> Self

Clears this Matching’s group clause

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

Trait Implementations

impl Clone for Matching

fn clone(&self) -> Matching

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Matching

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

Formats the value using the given formatter.

impl Display for Matching

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

Formats the value using the given formatter.

impl PartialEq for Matching

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