Struct Completion 

#[non_exhaustive]
pub struct Completion {
    pub values: Vec<String>,
    pub total: Option<u32>,
    pub has_more: Option<bool>,
}

Suggested values for one argument.

The host truncates Self::values to the limit MCP places on a single completion response and marks the result as having more, so a plugin may return everything it knows without tracking the protocol’s cap.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

values: Vec<String>

Suggestions, best first.

total: Option<u32>

How many exist in total, when the plugin knows and it exceeds what it returned.

has_more: Option<bool>

Whether more exist beyond Self::values.

Leave unset unless the plugin itself truncated; the host sets it when its own truncation drops values.

Implementations

impl Completion

pub fn none() -> Self

Suggest nothing. A valid answer, and the default.

pub fn new(values: impl IntoIterator<Item = String>) -> Self

Suggest values, best first.

pub fn with_total(self, total: u32) -> Self

Report how many suggestions exist in total.

pub fn with_has_more(self, has_more: bool) -> Self

Report that the plugin itself returned only part of what it knows.

Trait Implementations

impl Clone for Completion

fn clone(&self) -> Completion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Completion

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

Formats the value using the given formatter.

impl Default for Completion

fn default() -> Completion

Returns the “default value” for a type.

impl Eq for Completion

impl PartialEq for Completion

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

Equality operator ==.

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

Inequality operator !=.
