Struct bson::oid::ObjectId

pub struct ObjectId { /* fields omitted */ }

A wrapper around raw 12-byte ObjectId representations.

Methods

impl ObjectId

fn new() -> Result<ObjectId>

Generates a new ObjectID, represented in bytes. See the docs for more information.

fn with_bytes(bytes: [u8; 12]) -> ObjectId

Constructs a new ObjectId wrapper around the raw byte representation.

fn with_string(s: &str) -> Result<ObjectId>

Creates an ObjectID using a 12-byte (24-char) hexadecimal string.

fn with_timestamp(time: u32) -> ObjectId

Creates a dummy ObjectId with a specific generation time. This method should only be used to do range queries on a field containing ObjectId instances.

fn bytes(&self) -> [u8; 12]

Returns the raw byte representation of an ObjectId.

fn timestamp(&self) -> u32

Retrieves the timestamp (seconds since epoch) from an ObjectId.

fn machine_id(&self) -> u32

Retrieves the machine id associated with an ObjectId.

fn process_id(&self) -> u16

Retrieves the process id associated with an ObjectId.

fn counter(&self) -> u32

Retrieves the increment counter from an ObjectId.

Trait Implementations

impl Clone for ObjectId

fn clone(&self) -> ObjectId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for ObjectId

fn eq(&self, __arg_0: &ObjectId) -> bool

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

fn ne(&self, __arg_0: &ObjectId) -> bool

This method tests for !=.

impl PartialOrd for ObjectId

fn partial_cmp(&self, __arg_0: &ObjectId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &ObjectId) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &ObjectId) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &ObjectId) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &ObjectId) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
