pub trait MdfTrait

Trait functions

new

Makes a new Mdf value from month, day and YearFlags.

This method doesn’t fully validate the range of the month and day parameters, only as much as what can’t be deferred until later. The year flags are trusted to be correct.

Errors

Returns None if month > 12 or day > 31.

Fully qualified path: chrono::internals::MdfTrait::new

fn new(month: u32, day: u32, flags: YearFlags) -> Option<Mdf>

from_ol

Makes a new Mdf value from an i32 with an ordinal and a leap year flag, and year flags.

The ol is trusted to be valid, and the flags are trusted to match it.

fn from_ol(ol: i32, flags: YearFlags) -> Mdf

month

Returns the month of this Mdf.

Fully qualified path: chrono::internals::MdfTrait::month

fn month(self: @Mdf) -> u32

with_month

Replaces the month of this Mdf, keeping the day and flags.

Errors

Returns None if month > 12.

Fully qualified path: chrono::internals::MdfTrait::with_month

fn with_month(self: @Mdf, month: u32) -> Option<Mdf>

day

Returns the day of this Mdf.

Fully qualified path: chrono::internals::MdfTrait::day

fn day(self: @Mdf) -> u32

with_day

Replaces the day of this Mdf, keeping the month and flags.

Errors

Returns None if day > 31.

Fully qualified path: chrono::internals::MdfTrait::with_day

fn with_day(self: @Mdf, day: u32) -> Option<Mdf>

with_flags

Replaces the flags of this Mdf, keeping the month and day.

Fully qualified path: chrono::internals::MdfTrait::with_flags

fn with_flags(self: @Mdf, flags: YearFlags) -> Mdf

ordinal

Returns the ordinal that corresponds to this Mdf.

This does a table lookup to calculate the corresponding ordinal. It will return an error if the Mdl turns out not to be a valid date.

Errors

Returns None if month == 0 or day == 0, or if a the given day does not exist in the given month.

Fully qualified path: chrono::internals::MdfTrait::ordinal

fn ordinal(self: @Mdf) -> Option<u32>

ordinal_and_flags

Returns the ordinal that corresponds to this Mdf, encoded as a value including year flags.

This does a table lookup to calculate the corresponding ordinal. It will return an error if the Mdl turns out not to be a valid date.

Errors

Returns None if month == 0 or day == 0, or if a the given day does not exist in the given month.
