Implementations

impl ContentMatch

pub fn parse(str: String, nodes: &HashMap<String, NodeType>) -> ContentMatch

pub fn empty() -> Self

pub fn match_type(&self, node_type: &NodeType) -> Option<&ContentMatch>

pub fn match_fragment( &self, frag: &[Node], schema: &Schema, ) -> Option<&ContentMatch>

pub fn fill( &self, after: &Vec<Node>, to_end: bool, schema: &Schema, ) -> Option<Vec<Node>>

根据内容匹配规则填充节点

参数

• after: 待匹配的节点列表
• to_end: 是否需要匹配到结束状态
• schema: 当前使用的文档模式

返回值

返回填充后的节点列表，如果无法匹配则返回None

pub fn edge_count(&self) -> usize

pub fn edge(&self, n: usize) -> Result<&MatchEdge, String>

Trait Implementations

impl Clone for ContentMatch

fn clone(&self) -> ContentMatch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ContentMatch

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

Formats the value using the given formatter.

impl Default for ContentMatch

fn default() -> ContentMatch

Returns the “default value” for a type.

impl Display for ContentMatch

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

Formats the value using the given formatter.

impl Ord for ContentMatch

fn cmp(&self, other: &Self) -> 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 ContentMatch

fn eq(&self, other: &ContentMatch) -> 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 ContentMatch

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