Struct OutputM

pub struct OutputM<M: Mode, EM: Mode, S: IsStreaming> { /* private fields */ }

Holds the parser execution modifiers: output Mode, error Mode and streaming behaviour for input data

Trait Implementations

impl<M: Mode, EM: Mode, S: IsStreaming> OutputMode for OutputM<M, EM, S>

type Output = M

Defines the Mode for the output type. Emit will generate the value, Check will apply the parser but will only generate () if successful. This can be used when verifying that the input data conforms to the format without having to generate any output data

type Error = EM

Defines the Mode for the output type. Emit will generate the value, Check will apply the parser but will only generate () if an error happened. Emit should be used when we want to handle the error and extract useful information from it. Check is used when we just want to know if parsing failed and reject the data quickly.

type Incomplete = S

Indicates whether the input data is “complete”, ie we already have the entire data in the buffer, or if it is “streaming”, where more data can be added later in the buffer. In streaming mode, the parser will understand that a failure may mean that we are missing data, and will return a specific error branch, Err::Incomplete to signal it. In complete mode, the parser will generate a normal error
