Struct UserInOutIovec 

pub struct UserInOutIovec { /* private fields */ }

A wrapper around a userspace array of zx_iovec_t for read-write operations.

Implementations

impl UserInOutIovec

pub const fn new(vector: UserInPtr<zx_iovec_t>, count: usize) -> Self

Constructs a new UserInOutIovec.

pub fn is_null(&self) -> bool

Returns true if the underlying pointer is null.

pub fn get_total_capacity(&self) -> Result<usize, Status>

Calculates the total capacity across all iovecs.

pub fn for_each<F>(&self, cb: F) -> Result<(), Status>

where F: FnMut(UserInOutPtr<u8>, usize) -> Result<(), Status>,

Iterates through the iovecs and invokes the callback for each user pointer and capacity.
