Struct gnunet_sys::GNUNET_MQ_MessageHandler

#[repr(C)]pub struct GNUNET_MQ_MessageHandler {
    pub mv: GNUNET_MQ_MessageValidationCallback,
    pub cb: GNUNET_MQ_MessageCallback,
    pub cls: *mut c_void,
    pub type_: u16,
    pub expected_size: u16,
}

Message handler for a specific message type.

Fields

mv: GNUNET_MQ_MessageValidationCallback

Callback to validate a message of the specified @e type. The closure given to @e mv will be this struct (not @e ctx). Using NULL means only size-validation using @e expected_size. In this case, @e expected_size must be non-zero.

cb: GNUNET_MQ_MessageCallback

Callback, called every time a new message of the specified @e type has been received. The closure given to @e mv will be this struct (not @e ctx).

cls: *mut c_void

Closure for @e mv and @e cb.

type_: u16

Type of the message this handler covers, in host byte order.

expected_size: u16

Expected size of messages of this type. Minimum size of the message if @e mv is non-NULL. Messages of the given type will be discarded (and the connection closed with an error reported to the application) if they do not have the right size.
