Trait IntoCStrArray

    type CStrArray: AsCStrArray;

    // Required method
    fn into_c_str_array(self) -> Self::CStrArray;
}

Types that can be converted into an AsCStrArray

This trait is the bound that is actually required for the Exec::execve function. By using this trait instead of AsCStrArray directly, execve can accept types that either implement AsCStrArray directly or can be converted into one, such as Vec<CString>. This reduces the need for users to manually convert their string collections into BorrowedCStrss or other AsCStrArray implementors before passing them to execve.

Note that implementations of this trait may perform conversions that involve heap allocations, so users should be aware of the potential performance implications when using this trait with types that do not directly implement AsCStrArray.

This trait is currently sealed to avoid breakage in a possible future extension. Please open an issue if you have a use case for implementing this trait for a type defined outside this crate and would like it to be unsealed.

Required Associated Types

type CStrArray: AsCStrArray

The type that self can be converted into, which must implement AsCStrArray.

Required Methods

fn into_c_str_array(self) -> Self::CStrArray

Converts self into a type that implements AsCStrArray.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl<'a, T> IntoCStrArray for &'a [T]

where T: AsRef<CStr>,

Converts a slice of &CStrs into a BorrowedCStrs. (See BorrowedCStrs::from_iter.)

type CStrArray = BorrowedCStrs<'a>

fn into_c_str_array(self) -> BorrowedCStrs<'a>

impl<T> IntoCStrArray for Vec<T>

where T: Into<CString>,

Converts a Vec<T> into an OwnedCStrs. (See OwnedCStrs::from_iter.)

type CStrArray = OwnedCStrs

fn into_c_str_array(self) -> OwnedCStrs

Implementors

impl<T: AsCStrArray> IntoCStrArray for T

Any type that implements AsCStrArray can be converted into a AsCStrArray by identity conversion.

type CStrArray = T
