Struct curl::multi::Message

pub struct Message<'multi> { /* fields omitted */ }

Message from the messages function of a multi handle.

Currently only indicates whether a transfer is done.

Methods

impl<'multi> Message<'multi>

pub fn result(&self) -> Option<Result<(), Error>>

If this message indicates that a transfer has finished, returns the result of the transfer in Some.

If the message doesn't indicate that a transfer has finished, then None is returned.

Note that the result*_for methods below should be preferred as they provide better error messages as the associated error data on the handle can be associated with the error type.

pub fn result_for(&self, handle: &EasyHandle) -> Option<Result<(), Error>>

Same as result, except only returns Some for the specified handle.

Note that this function produces better error messages than result as it uses take_error_buf to associate error information with the returned error.

pub fn result_for2<H>(
    &self,
    handle: &Easy2Handle<H>
) -> Option<Result<(), Error>>

Same as result, except only returns Some for the specified handle.

Note that this function produces better error messages than result as it uses take_error_buf to associate error information with the returned error.

pub fn is_for(&self, handle: &EasyHandle) -> bool

Returns whether this easy message was for the specified easy handle or not.

pub fn is_for2<H>(&self, handle: &Easy2Handle<H>) -> bool

Same as is_for, but for Easy2Handle.

pub fn token(&self) -> Result<usize, Error>

Returns the token associated with the easy handle that this message represents a completion for.

This function will return the token assigned with EasyHandle::set_token. This reads the CURLINFO_PRIVATE field of the underlying *mut CURL.
