Struct rustls_ffi::rslice::rustls_slice_str

pub struct rustls_slice_str<'a> { /* private fields */ }

A read-only view of a slice of multiple Rust &str’s (that is, multiple strings). Like rustls_str, this guarantees that each string contains UTF-8 and no NUL bytes. Strings are not NUL-terminated.

This is used to pass data from rustls-ffi to callback functions provided by the user of the API. Because Vec and slice are not #[repr(C)], we can’t provide a straightforward data and len structure. Instead, we provide access via a pointer to an opaque struct and accessor methods. Internally, the pointee is a &[&str].

The memory exposed is available as specified by the function using this in its signature. For instance, when this is a parameter to a callback, the lifetime will usually be the duration of the callback. Functions that receive one of these must not call its methods beyond the allowed lifetime.
