Struct EmitOptions 

pub struct EmitOptions {
    pub style: EmitStyle,
    pub redundant_until: Option<i64>,
    pub range: Option<RangeSpec>,
}

Full emission options: an EmitStyle plus the optional -R redundant-tail bound (T10.3).

redundant_until is reference zic’s -R @hi. It is meaningful only with EmitStyle::ZicSlim: it keeps the otherwise-droppable, footer-governed explicit transitions out to this UT instant (inclusive), so old readers that ignore the POSIX footer still see correct timestamps up to that point. It is not fat mode (-b) and not range truncation (-r). With the fat-style default it is a no-op (everything is kept already). EmitStyle converts into EmitOptions with redundant_until: None, so callers that don’t use -R are unchanged.

Fields

style: EmitStyle

redundant_until: Option<i64>

range: Option<RangeSpec>

-r '[@lo][/@hi]' range truncation (T10.4d). A distinct input from Self::redundant_until — they both inform what is emitted but are never merged: -R widens what slim keeps, -r reshapes the representable interval (and introduces the -00 “local time unspecified” boundary type(s)). None = no truncation.

Trait Implementations

impl Clone for EmitOptions

fn clone(&self) -> EmitOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for EmitOptions

impl Debug for EmitOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for EmitOptions

fn default() -> Self

Returns the “default value” for a type.

impl Eq for EmitOptions

impl From<EmitStyle> for EmitOptions

fn from(style: EmitStyle) -> Self

Converts to this type from the input type.

impl PartialEq for EmitOptions

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
