Struct mongodb::oid::ObjectId

pub struct ObjectId { /* fields omitted */ }

A wrapper around raw 12-byte ObjectId representations.

Methods

impl ObjectId

pub fn new() -> Result<ObjectId, Error>

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

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

Constructs a new ObjectId wrapper around the raw byte representation.

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

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

pub 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.

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

Returns the raw byte representation of an ObjectId.

pub fn timestamp(&self) -> u32

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

pub fn machine_id(&self) -> u32

Retrieves the machine id associated with an ObjectId.

pub fn process_id(&self) -> u16

Retrieves the process id associated with an ObjectId.

pub fn counter(&self) -> u32

Retrieves the increment counter from an ObjectId.

pub fn to_hex(&self) -> String

Convert the objectId to hex representation.

impl Eq for ObjectId

impl PartialEq<ObjectId> for ObjectId

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

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

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

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

impl PartialOrd<ObjectId> for ObjectId

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

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

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

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