Struct Span

pub struct Span {
    pub start: usize,
    pub end: usize,
    pub source_id: u16,
}

Fields

start: usize

end: usize

source_id: u16

A key representing the path of the source. Value is stored in prqlc’s SourceTree::source_ids.

Trait Implementations

impl Add<usize> for Span

type Output = Span

The resulting type after applying the + operator.

fn add(self, rhs: usize) -> Span

Performs the + operation.

impl Clone for Span

fn clone(&self) -> Span

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Span

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Span

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Span> for Range<usize>

fn from(a: Span) -> Self

Converts to this type from the input type.

impl JsonSchema for Span

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn always_inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Span

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

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.

impl Serialize for Span

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Span for Span

type Context = u16

Extra context used in a span.

type Offset = usize

A type representing a span’s start or end offset from the start of the input.

fn new(context: Self::Context, range: Range<Self::Offset>) -> Self

Create a new span given a context and an offset range.

fn context(&self) -> Self::Context

Return the span’s context.

fn start(&self) -> Self::Offset

Return the start offset of the span.

fn end(&self) -> Self::Offset

Return the end offset of the span.

impl Sub<usize> for Span

type Output = Span

The resulting type after applying the - operator.

fn sub(self, rhs: usize) -> Span

Performs the - operation.

impl Copy for Span

impl Eq for Span

impl StructuralPartialEq for Span
