Expand description
A validation definition.
Variants§
KnownFormat(Format)
Well-known validator formats as described in the JSON Schema Validation specification.
Length
A minimum and/or maximum length.
Can be used for strings, arrays, and objects.
When used for strings, applies to the number of characters. When used for arrays, applies to the number of items. When used for objects, applies to the number of properties.
Range
A minimum and/or maximum range, or bound.
Can only be used for numbers.
Pattern(String)
A regular expression pattern.
Can only be used for strings.

fn from_nested_meta(item: &NestedMeta) -> Result<Self, Error>
§fn from_meta(item: &Meta) -> Result<Self, Error>
fn from_meta(item: &Meta) -> Result<Self, Error>
Create an instance from a
syn::Meta
by dispatching to the format-appropriate
trait function. This generally should not be overridden by implementers. Read more§fn from_none() -> Option<Self>
fn from_none() -> Option<Self>
When a field is omitted from a parent meta-item,
from_none

recovery before a missing field error is generated. Read more§fn from_value(value: &Lit) -> Result<Self, Error>
fn from_value(value: &Lit) -> Result<Self, Error>
Create an instance from a literal value of either
foo = "bar"
or foo("bar")
.
This dispatches to the appropriate method based on the type of literal encountered,
and generally should not be overridden by implementers. Read morefn from_expr(expr: &Expr) -> Result<Self, Error>
