SourceTag

Struct SourceTag 

Source
pub struct SourceTag(/* private fields */);
Expand description

A static C-string tag identifying the source location ("file:line") where a lock is acquired.

Used with RawMonitoredSpinlock to pass critical section names to the kernel lockup detector. Construct via the source_tag! macro, which is the Rust equivalent of C++ SOURCE_TAG.

Implementations§

Source§

impl SourceTag

Source

pub const unsafe fn from_bytes_with_nul_unchecked(bytes: &'static [u8]) -> Self

Creates a SourceTag from a static null-terminated byte slice without checking for interior null bytes.

§Safety

bytes must be a valid null-terminated C string (ending in \0 with no interior \0 bytes).

Source

pub const fn from_cstr(cstr: &'static CStr) -> Self

Creates a SourceTag from a static CStr.

Source

pub const fn as_ptr(&self) -> *const c_char

Returns a pointer to the underlying null-terminated C string.

Source

pub const fn as_cstr(&self) -> &'static CStr

Returns the underlying CStr.
