Enum UnknownPolicy

pub enum UnknownPolicy {
    Generate,
    Allow,
    Deny,
}

Policy to apply to external types described by schema extensions whose crates are not explicitly specified.

Variants

Generate

Generate the type rather according to the schema.

Allow

Use the specified type by path (this will result in a compile error if one of the crates is not an existing dependency). Note that this ignores compatibility requirements specified by the schema extension and may result in subtle failures if the crate used is incompatible with the version that produced the schema.

Deny

If an unknown crate is encountered, generate a compiler warning indicating the crate that must be specified to proceed along with version constraints. This affords users an opportunity to specify the specific crate version to use (or the user may explicitly deny use of that crate).

Trait Implementations

impl Clone for UnknownPolicy

fn clone(&self) -> UnknownPolicy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnknownPolicy

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

Formats the value using the given formatter.

impl Default for UnknownPolicy

fn default() -> UnknownPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UnknownPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for UnknownPolicy

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