Enum QueryUpdate 

#[non_exhaustive]
pub enum QueryUpdate {
    Timeout,
    Done,
}

App-level events emitted by Query::poll().

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Timeout

Query’s retry budget expired without finding a match.

Done

Query is finished (caller cancelled or completed enough answers).

Implementations

impl QueryUpdate

pub const fn is_timeout(&self) -> bool

Returns true if this value is of type Timeout. Returns false otherwise

pub const fn is_done(&self) -> bool

Returns true if this value is of type Done. Returns false otherwise

impl QueryUpdate

pub fn unwrap_timeout(self)

Unwraps this value to the QueryUpdate::Timeout variant. Panics if this value is of any other type.

pub fn unwrap_timeout_ref(&self)

Unwraps this reference to the QueryUpdate::Timeout variant. Panics if this value is of any other type.

pub fn unwrap_done(self)

Unwraps this value to the QueryUpdate::Done variant. Panics if this value is of any other type.

pub fn unwrap_done_ref(&self)

Unwraps this reference to the QueryUpdate::Done variant. Panics if this value is of any other type.

impl QueryUpdate

pub fn try_unwrap_timeout(self) -> Result<(), TryUnwrapError<QueryUpdate>>

Attempts to unwrap this value to the QueryUpdate::Timeout variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_timeout_ref(&self) -> Result<(), TryUnwrapError<&QueryUpdate>>

Attempts to unwrap this reference to the QueryUpdate::Timeout variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_done(self) -> Result<(), TryUnwrapError<QueryUpdate>>

Attempts to unwrap this value to the QueryUpdate::Done variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.

pub fn try_unwrap_done_ref(&self) -> Result<(), TryUnwrapError<&QueryUpdate>>

Attempts to unwrap this reference to the QueryUpdate::Done variant. Returns a [TryUnwrapError] with the original value if this value is of any other type.
