Implementations

impl Span

pub fn new(file: &str) -> Self

Trait Implementations

impl Clone for Span

fn clone(&self) -> Span

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 Default for Span

fn default() -> Self

Returns the “default value” for a type.

impl Display for Span

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

Formats the value using the given formatter.

impl Hash for Span

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 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 SchemeCompatible for Span

fn rtd() -> Arc<RecordTypeDescriptor>

The Record Type Descriptor of the value. Can be constructed at runtime, but cannot change.

fn extract_embedded_record( &self, _rtd: &Arc<RecordTypeDescriptor>, ) -> Option<Gc<dyn SchemeCompatible>>

Extract the embedded record type with the matching record type descriptor if it exists.

fn get_field(&self, k: usize) -> Result<Value, Exception>

Fetch the kth field of the record.

fn set_field(&self, k: usize, _val: Value) -> Result<(), Exception>

Set the kth field of the record.

impl Trace for Span

unsafe fn visit_children(&self, visitor: &mut dyn FnMut(OpaqueGcPtr))

Safety

unsafe fn finalize(&mut self)

Safety
