Struct PmpxStr 

#[repr(C)]
pub struct PmpxStr {
    pub ptr: *const u8,
    pub len: usize,
}

A cross-boundary string: pointer + length, with no NUL terminator required. ptr / len describe raw bytes (possibly a path or a command-line argument) which on Unix need not be valid UTF-8; UTF-8 is checked only where the data is explicitly required to be text, and a failure returns PMPX_ERR_INVALID_ARGS rather than UB. It carries a length instead of relying on NUL because the pointer returned by str::as_ptr() is not guaranteed to be followed by a NUL.

Fields

ptr: *const u8

Start address. May be null when len == 0.

len: usize

Length in bytes.

Implementations

impl PmpxStr

pub const EMPTY: PmpxStr

Empty. len == 0 with a null pointer – in cwd this means “no override”.

pub const fn from_static(s: &'static str) -> Self

Build from a 'static string (const so that the static vtable of export! can be filled in at compile time).

pub const fn is_empty(&self) -> bool

Whether it is empty.
