Implementations§

Source§

impl TimeDelta

Source

pub fn from_components(hours: i64, mins: i64, secs: i64, ms: i64) -> TimeDelta

Create this time type from all time components.

The components can be negative and/or exceed the its natural limits without error. For example from_components(0, 0, 3, -2000) is the same as from_components(0, 0, 1, 0).

Source

pub fn from_msecs(ms: i64) -> TimeDelta

Create the time type from a given number of milliseconds.

Source

pub fn from_csecs(ms: i64) -> TimeDelta

Create the time type from a given number of hundreth seconds (10 milliseconds).

Source

pub fn from_secs(ms: i64) -> TimeDelta

Create the time type with a given number of seconds.

Source

pub fn from_mins(mins: i64) -> TimeDelta

Create the time type with a given number of minutes.
