Struct CapabilityReply 

pub struct CapabilityReply<'a> { /* private fields */ }

A terminal host’s capability reply, with borrowed state and kind lists.

Advertise only capabilities the host implements. Omitted lists use the fixed revision 0.4 defaults; explicit empty lists advertise no support. A default reply has the same bytes as a query. On terminal-to-program input, interpret parser::Event::Query using the caller’s pending-query state.

Implementations

impl<'a> CapabilityReply<'a>

pub const fn new() -> Self

Uses the fixed revision 0.4 defaults for both omitted lists.

pub const fn states(self, states: &'a [State]) -> Self

Advertises these states in order; an empty slice advertises none.

pub const fn kinds(self, kinds: &'a [Kind]) -> Self

Advertises these blocking reasons in order; an empty slice advertises none.

pub fn write_to<W: Write + ?Sized>(self, output: &mut W) -> Result<(), Error>

Encodes the complete reply before writing to the caller’s writer. Uses no heap allocation and does not flush.

Errors

Returns parser::Error::Limit wrapped in Error::Parser before any output if the reply exceeds the complete-frame cap. Writer failures return Error::Io and can leave a partial frame.

Trait Implementations

impl<'a> Clone for CapabilityReply<'a>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for CapabilityReply<'a>

impl<'a> Debug for CapabilityReply<'a>

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

Formats the value using the given formatter.

impl<'a> Default for CapabilityReply<'a>

fn default() -> Self

Returns the “default value” for a type.
