Struct StringRef 

#[repr(transparent)]
pub struct StringRef(pub ThinStr<'static>);

Represents a handle to a string that can be retrieved by the string set. The exact representation is not a public detail; it is only available so that it is known for FFI size and alignment.

Some StringRefs refer to well-known strings, which always exist in every string table.

The caller needs to ensure the string set it was created from always exists when a StringId is dereferenced.

Implementations

impl StringRef

pub fn into_raw(self) -> NonNull<c_void>

pub unsafe fn from_raw(this: NonNull<c_void>) -> Self

Re-creates a StringRef created by StringRef::into_raw.

Safety

this needs to be created from ``StringRef::into_raw` and the set it belongs to should still be alive.

impl StringRef

pub const EMPTY: StringRef

pub const END_TIMESTAMP_NS: StringRef

pub const LOCAL_ROOT_SPAN_ID: StringRef

pub const TRACE_ENDPOINT: StringRef

pub const SPAN_ID: StringRef

Trait Implementations

impl Clone for StringRef

fn clone(&self) -> StringRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringRef

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

Formats the value using the given formatter.

impl Default for StringRef

fn default() -> Self

Returns the “default value” for a type.

impl From<&StringRef> for StringRef

fn from(value: &StringRef) -> Self

Converts to this type from the input type.

impl Hash for StringRef

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 StringRef

fn eq(&self, other: &StringRef) -> 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.
