Struct PatternElement 

Source 
pub struct PatternElement<Weight> { /* private fields */ }
Expand description

Struct that holds all relevant matching information for a single node/edge.

Implementations§

Source§

impl<Weight> PatternElement<Weight>

Holds the constructor for Matcher.

Source

pub fn new(condition: Box<Matcher<Weight>>, ignore: bool) -> Self

Creates a new Matcher struct. If ignore is true, the node/edge will be hidden from the result graph.

Source

pub fn should_appear(&self) -> bool

Checks the matched node should appear in the result graph.

Source

pub fn may_match(&self, element: &Weight) -> bool

Tests if the given element matches the condition this matcher.
