Struct Span 

pub struct Span<'db> {
    pub anchor: Anchor<'db>,
    pub start: Offset,
    pub end: Offset,
}

A span within the input.

The offsets are stored relative to the start of the anchor, which is some item (e.g., a class, function, etc). The use of relative offsets avoids incremental churn if lines or content is added before/after the definition.

Fields

anchor: Anchor<'db>

start: Offset

end: Offset

Trait Implementations

impl<'db> Clone for Span<'db>

fn clone(&self) -> Span<'db>

Returns a duplicate 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<'db> Hash for Span<'db>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'db> IntoOptionSpan<'db> for Span<'db>

fn into_opt_span(self) -> Option<Span<'db>>

impl<'db> Ord for Span<'db>

fn cmp(&self, other: &Span<'db>) -> 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<'db> PartialEq for Span<'db>

fn eq(&self, other: &Span<'db>) -> 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<'db> PartialOrd for Span<'db>

fn partial_cmp(&self, other: &Span<'db>) -> 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<'db> Spanned<'db> for Span<'db>

fn span(&self, _db: &'db dyn Db) -> Span<'db>

impl<'db> Update for Span<'db>

unsafe fn maybe_update(old_pointer_: *mut Self, new_value_: Self) -> bool

Returns

impl<'db> Copy for Span<'db>

impl<'db> Eq for Span<'db>

impl<'db> StructuralPartialEq for Span<'db>
