Enum PaxValue 

pub enum PaxValue<T> {
    Value(T),
    Deleted,
}

A parsed pax value, including an explicit deletion tombstone.

Deletion tombstones are needed because pax has special semantics for empty (i.e. deleted) pax records: they’re considered to delete “any header block field, previously entered extended header value, or global extended header value of the same name.”

This is a distinct state from “missing,” which allows for fallbacks to e.g. global pax headers or the equivalent ustar field.

Variants

Value(T)

This record sets or overrides the attribute.

Deleted

This record deletes the attribute from its applicable scope.

Trait Implementations

impl<T: Clone> Clone for PaxValue<T>

fn clone(&self) -> PaxValue<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for PaxValue<T>

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

Formats the value using the given formatter.

impl<T: Eq> Eq for PaxValue<T>

impl<T: FromStr> FromStr for PaxValue<T>

type Err = <T as FromStr>::Err

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl<T: PartialEq> PartialEq for PaxValue<T>

fn eq(&self, other: &PaxValue<T>) -> 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.
