Enum cargo_toml::Inheritable

pub enum Inheritable<T> {
    Set(T),
    Inherited {
        workspace: bool,
    },
}

Placeholder for a property that may be missing from its package, and needs to be copied from a Workspace.

Variants

Set(T)

Inherited

Fields

workspace: bool

Always true (this is for serde)

Implementations

impl<T> Inheritable<T>

pub fn as_ref(&self) -> Inheritable<&T>

pub fn is_set(&self) -> bool

You can read the value

pub fn get(&self) -> Result<&T, Error>

pub fn set(&mut self, val: T)

pub fn as_mut(&mut self) -> Inheritable<&mut T>

pub fn get_mut(&mut self) -> Result<&mut T, Error>

Fails if inherited

pub fn unwrap(self) -> T

Panics if inherited

pub fn inherit(&mut self, other: &T)

where T: Clone,

Copy from workspace if needed

impl<T> Inheritable<Vec<T>>

pub fn is_empty(&self) -> bool

False if inherited and unknown

impl<T: Default + PartialEq> Inheritable<T>

pub fn is_default(&self) -> bool

False if inherited and unknown

Trait Implementations

impl<T: Clone> Clone for Inheritable<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for Inheritable<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for Inheritable<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'de, T> Deserialize<'de> for Inheritable<T>

where T: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Inheritable<T>> for Option<T>

fn from(val: Inheritable<T>) -> Self

None if inherited

impl<T> From<Option<T>> for Inheritable<T>

fn from(val: Option<T>) -> Self

Inherits if None

impl<T: PartialEq> PartialEq for Inheritable<T>

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<T> Serialize for Inheritable<T>

where T: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T: Copy> Copy for Inheritable<T>
