Struct InputSpan

pub struct InputSpan {
    pub start_line: u32,
    pub start_column: u32,
    pub start: u32,
    pub len: u32,
    pub tempered: bool,
}

Represents a span of text in the input source, tracking location information.

This struct stores the starting line, column, absolute position and length of a span of text, along with a flag indicating if the span has been modified.

Fields

start_line: u32

start_column: u32

start: u32

len: u32

tempered: bool

Implementations

impl InputSpan

pub fn from_pair(pair: &Pair<'_, Rule>) -> Self

Creates a new InputSpan from a Pest parser Pair.

Arguments

• pair - Reference to a Pest parser Pair

pub fn from_span(span: Span<'_>) -> Self

Creates a new InputSpan from a Pest Span.

Arguments

• span - A Pest Span object

pub fn span_text<'a>(&self, text: &'a str) -> Result<&'a str, String>

Extracts the text corresponding to this span from the given source text.

Arguments

• text - The source text to extract from

Returns

• Ok(&str) - The extracted text slice if the span is valid
• Err(String) - Error message if the span is out of bounds

Trait Implementations

impl Clone for InputSpan

fn clone(&self) -> InputSpan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputSpan

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

Formats the value using the given formatter.

impl Default for InputSpan

fn default() -> InputSpan

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for InputSpan

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for InputSpan

fn eq(&self, other: &InputSpan) -> 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 Serialize for InputSpan

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for InputSpan
