Struct safer_ffi::char_p::char_p_boxed

pub struct char_p_boxed(/* private fields */);

A #[repr(c)] null-terminated UTF-8 encoded string, for compatibility with both the char * C API and Rust str.

This is an owned / heap-allocated version, much like Box<str> / Box<CStr> but for it being a slim pointer.

C Layout

• ptr :: NonNullOwned < c_char >

Trait Implementations

impl Clone for char_p_boxed

Available on crate feature alloc only.

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

Available on crate feature alloc only.

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

Formats the value using the given formatter.

impl Display for char_p_boxed

impl From<CString> for char_p_boxed

Available on crate feature std only.

Panic

Panics if the CString is not valid UTF-8.

fn from(s: CString) -> char_p_boxed

Converts to this type from the input type.

impl PartialEq for char_p_boxed

Available on crate feature alloc only.

fn eq(&self, other: &Self) -> bool
