Struct Buffer 

pub struct Buffer<const N: usize> { /* private fields */ }

Available on non-crate feature lock only.

A null terminated buffer of N bytes, on the stack while what it holds fits.

Both directions go through it: an argument is copied in and handed to CSPICE as a pointer, and an output is zeroed, written by CSPICE, then read back.

Implementations

impl<const N: usize> Buffer<N>

pub fn from_text(value: &str) -> Self

A null terminated copy of value.

Panics

Panics if value contains an interior null byte: C has no way to represent it, so passing one along would silently truncate the argument.

pub fn with_len(len: usize) -> Self

A zeroed buffer of len bytes, for CSPICE to write a string into.

pub fn as_mut_ptr(&mut self) -> *mut SpiceChar

The pointer to hand to CSPICE.

pub fn into_string(self) -> String

Read the buffer back as a Rust string.
