Struct ResponseHead 

pub struct ResponseHead {
    pub warnings: Vec<Warning>,
    pub envelope: Envelope,
}

A response head: zero or more warnings followed by an envelope.

Fields

warnings: Vec<Warning>

envelope: Envelope

Implementations

impl ResponseHead

pub fn ok(token: StateToken) -> Self

pub fn err(code: ErrorCode, args: Vec<String>) -> Self

pub fn with_warning(self, w: Warning) -> Self

pub fn encode(&self) -> String

Encode the head: warnings (one per line) then the envelope line. Does not emit the trailing blank line that terminates a full response — callers compose that.

pub fn parse(input: &str) -> Result<Self>

Parse a head from a multi-line string. Stops at the envelope line (anything after that line is the body, which the caller handles).

Trait Implementations

impl Clone for ResponseHead

fn clone(&self) -> ResponseHead

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResponseHead

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ResponseHead

fn eq(&self, other: &ResponseHead) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
