}Expand description
A Value represents a value of certain type.
The purpose of a Value is to include field values or parameters in
ConstraintViolations in a type that allows to display the value in a
localized format as part of a user facing error message.
It has variants for the basic types that are used in most applications.
Important types of 3rd party crates are supported through optional crate features:
| supported type | crate feature | 3rd party crate |
|---|---|---|
BigInt | num-bigint | num-bigint |
BigDecimal | bigdecimal | bigdecimal |
NaiveDate | chrono | chrono |
DateTime | chrono | chrono |
The From trait is implemented for the underlying types. Additionally
there are implementations of the From trait for the primitive types i8,
i16, i64, u8, u16, u32, u64.
u32 values greater than i32::max_value() are converted to Long(i64).
§Panics
Converting u64 values greater than i64::max_value() has an unreliable
behavior and might panic.
§Notes
The list of supported types is very opinionated and may not fit all kind of applications. Please file and issue if you feel that support for another type may be useful!
