Struct ExtraData 

pub struct ExtraData(/* private fields */);

Extra data associated with a package.

This type wraps a vector of ExtraDataEntry items enforcing that it includes a valid pkgtype entry.

Can be created from a Vec<ExtraDataEntry> or ExtraDataEntry using TryFrom::try_from.

Implementations

impl ExtraData

pub fn pkg_type(&self) -> PackageType

Returns the package type.

pub fn len(&self) -> usize

Returns the number of extra data entries.

pub fn is_empty(&self) -> bool

Returns true if there are no extra data entries.

Due to the invariant enforced in TryFrom, this will always return false and is only included for consistency with Vec::is_empty in the standard library.

Trait Implementations

impl AsRef<[ExtraDataEntry]> for ExtraData

fn as_ref(&self) -> &[ExtraDataEntry]

Returns a reference to the inner Vec<ExtraDataEntry>.

impl Clone for ExtraData

fn clone(&self) -> ExtraData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtraData

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

Formats the value using the given formatter.

impl From<ExtraData> for Vec<ExtraDataEntry>

fn from(value: ExtraData) -> Self

Converts the ExtraData into a Vec<ExtraDataEntry>.

impl IntoIterator for ExtraData

fn into_iter(self) -> Self::IntoIter

Consumes the ExtraData and returns an iterator over ExtraDataEntry items.

type Item = ExtraDataEntry

The type of the elements being iterated over.

type IntoIter = IntoIter<ExtraDataEntry>

Which kind of iterator are we turning this into?

impl PartialEq for ExtraData

fn eq(&self, other: &ExtraData) -> 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.

impl Serialize for ExtraData

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<ExtraDataEntry> for ExtraData

fn try_from(value: ExtraDataEntry) -> Result<Self, Self::Error>

Creates an ExtraData from a single ExtraDataEntry.

Delegates to TryFrom::try_from for Vec<ExtraDataEntry>.

Errors

If the TryFrom::try_from for Vec<ExtraDataEntry> returns an error.

type Error = Error

The type returned in the event of a conversion error.

impl TryFrom<Vec<ExtraDataEntry>> for ExtraData

fn try_from(value: Vec<ExtraDataEntry>) -> Result<Self, Self::Error>

Creates an ExtraData from a vector of ExtraDataEntry.

Errors

Returns an error in the following cases:

• if the value does not contain a pkgtype key.
• if the pkgtype entry does not contain a valid package type.

type Error = Error

The type returned in the event of a conversion error.
