A trait for owned JSON values.

Required Associated Types

type Borrowed<'a>: JsonRef<'a, Owned = Self> where Self: 'a

The type of borrowed JSON values.

Required Methods

fn as_ref(&self) -> Self::Borrowed<'_>

Returns a reference to the JSON value.

fn null() -> Self

Returns a null value.

fn bool(b: bool) -> Self

Returns a boolean value.

fn from_u64(v: u64) -> Self

Returns a number value from u64.

fn from_i64(v: i64) -> Self

Returns a number value from i64.

fn from_f64(v: f64) -> Self

Returns a number value from f64.

fn from_number(n: Number) -> Self

Returns a number value.

fn from_string(s: &str) -> Self

Returns a string value.

fn object<'a, I: IntoIterator<Item = (&'a str, Self)>>(i: I) -> Self

Returns an object.

Provided Methods

fn borrow<'b, 'a: 'b>(p: Self::Borrowed<'a>) -> Self::Borrowed<'b>

Narrow down the lifetime of a borrowed value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
