Struct chrono::naive::datetime::NaiveDateTime [] [src]

pub struct NaiveDateTime { /* fields omitted */ }

ISO 8601 combined date and time without timezone.

Methods

impl NaiveDateTime
[src]

Makes a new NaiveDateTime from date and time components. Equivalent to date.and_time(time) and many other helper constructors on NaiveDate.

Makes a new NaiveDateTime from the number of non-leap seconds since the midnight UTC on January 1, 1970 (aka "UNIX timestamp") and the number of nanoseconds since the last whole non-leap second.

Panics on the out-of-range number of seconds and/or invalid nanosecond.

Makes a new NaiveDateTime from the number of non-leap seconds since the midnight UTC on January 1, 1970 (aka "UNIX timestamp") and the number of nanoseconds since the last whole non-leap second.

Returns None on the out-of-range number of seconds and/or invalid nanosecond.

Deprecated: Same to NaiveDateTime::from_timestamp.

Deprecated: Same to NaiveDateTime::from_timestamp_opt.

Parses a string with the specified format string and returns a new NaiveDateTime. See the format::strftime module on the supported escape sequences.

Retrieves a date component.

Retrieves a time component.

Returns the number of non-leap seconds since the midnight on January 1, 1970.

Note that this does not account for the timezone! The true "UNIX timestamp" would count seconds since the midnight UTC on the epoch.

Returns the number of milliseconds since the last whole non-leap second.

The return value ranges from 0 to 999, or for leap seconds, to 1,999.

Returns the number of microseconds since the last whole non-leap second.

The return value ranges from 0 to 999,999, or for leap seconds, to 1,999,999.

Returns the number of nanoseconds since the last whole non-leap second.

The return value ranges from 0 to 999,999,999, or for leap seconds, to 1,999,999,999.

Deprecated: Same to NaiveDateTime::timestamp.

Adds given Duration to the current date and time.

Returns None when it will result in overflow.

Subtracts given Duration from the current date and time.

Returns None when it will result in overflow.

Formats the combined date and time with the specified formatting items.

Formats the combined date and time with the specified format string. See the format::strftime module on the supported escape sequences.

impl Hash for NaiveDateTime
[src]

NaiveDateTime can be used as a key to the hash maps (in principle).

Practically this also takes account of fractional seconds, so it is not recommended. (For the obvious reason this also distinguishes leap seconds from non-leap seconds.)
