Struct chrono_simpletz::TimeZoneZst
source · pub struct TimeZoneZst<const HOUR: i32, const MINUTE: u32>;
Expand description
Represent Fixed Timezone with zero sized type and const generics.
HOUR
and MINUTE
must be in valid range(-23 <= HOUR <= 23 & MINUTE < 60)
, otherwise compile error will occur.
ⓘ
let tz = TimeZoneZst::<26, 0>::new();

sourcepub const OFFSET_SECS: i32 = _
pub const OFFSET_SECS: i32 = _
Gets the offset seconds. Should use FIXED_OFFSET
instead of using this directory.
sourcepub const IS_IN_VALID_RANGE: bool = _
pub const IS_IN_VALID_RANGE: bool = _
Checks whether the HOUR
and MINUTE
is in valid range(-23 <= HOUR <= 23 & MINUTE < 60)
. This does not check whether the timezone is known.
sourcepub const FIXED_OFFSET: FixedOffset = _
pub const FIXED_OFFSET: FixedOffset = _
Gets the FixedOffset
without creating a instance.
