Struct OptionOccurrence 

#[non_exhaustive]
pub struct OptionOccurrence<'a> {
    pub spec: &'a OptionSpec<'a>,
    pub location: Location,
    pub argument: Option<Field>,
}

Occurrence of an option

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

spec: &'a OptionSpec<'a>

Specification for this option

location: Location

Location of the field containing this option

argument: Option<Field>

Argument to this option

This value is always None for an option that does not take an argument.

This value always contains a field for an option that requires an argument.

If the option name and its argument are given in a single field, the field value is modified to contain only the option argument.

Trait Implementations

impl<'a> Clone for OptionOccurrence<'a>

fn clone(&self) -> OptionOccurrence<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for OptionOccurrence<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for OptionOccurrence<'a>

fn eq(&self, other: &OptionOccurrence<'a>) -> 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.
