Enum oracle::aq::DeqMode

pub enum DeqMode {
    Browse,
    Locked,
    Remove,
    RemoveNoData,
}

Modes that are possible when dequeuing messages from a queue

Warning: The type is unstable. It may be changed incompatibly by minor version upgrades.

Variants

Browse

Read the message without acquiring a lock on the message(equivalent to a SELECT statement).

Locked

Read the message and obtain a write lock on the message (equivalent to a SELECT FOR UPDATE statement).

Remove

Read the message and update or delete it. This is the default mode. Note that the message may be retained in the queue table based on retention properties.

RemoveNoData

Confirms receipt of the message but does not deliver the actual message content.

Trait Implementations

impl Clone for DeqMode

fn clone(&self) -> DeqMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeqMode

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

Formats the value using the given formatter.

impl PartialEq for DeqMode

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

This method tests for self and other values to be equal, and is used by ==.

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

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