Struct HurrayKvValue 

#[repr(C)]
pub struct HurrayKvValue {
    pub kind: u8,
    pub bool_value: bool,
    pub i64_value: i64,
    pub u64_value: u64,
    pub f64_value: f64,
    pub data: *const u8,
    pub data_len: usize,
    pub items: *const HurrayKvValue,
    pub item_count: usize,
}

One typed KV value: a kind tag and the fields that tag selects.

A flat tagged struct rather than a union, because every binding generator downstream of this header reads a struct correctly and few read a union well. Fields the tag does not select are zero on a read and ignored on a write.

Arrays nest one level and no further — the format forbids an array of arrays — so an items element is always a scalar.

Fields

kind: u8

Which HURRAY_KV_* kind this value is.

bool_value: bool

Set when kind is HURRAY_KV_BOOL.

i64_value: i64

Set when kind is HURRAY_KV_INT64.

u64_value: u64

Set when kind is HURRAY_KV_UINT64.

f64_value: f64

Set when kind is HURRAY_KV_FLOAT64.

data: *const u8

First byte of a HURRAY_KV_STRING or HURRAY_KV_BYTES payload, else null.

data_len: usize

Byte length of data. A string is UTF-8 and carries no NUL terminator.

items: *const HurrayKvValue

First element of a HURRAY_KV_ARRAY, else null.

item_count: usize

Number of elements at items.

Trait Implementations

impl Clone for HurrayKvValue

fn clone(&self) -> HurrayKvValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HurrayKvValue

impl Default for HurrayKvValue

fn default() -> Self

A zeroed value with a null kind, which is what a C caller gets from {0}.
