pub trait RequiredFieldDecode: FieldDecode {
// Required method
fn is_present(&self) -> bool;
}Expand description
This trait allows for decoding required fields.
Required Methods§
Sourcefn is_present(&self) -> bool
fn is_present(&self) -> bool

Operationally, it means that the start_decoding method has been accepted by the decoder but
the corresponding finish_decoding method has not been called yet.
