HurrayItemNode

Struct HurrayItemNode 

Source
#[repr(C)]
pub struct HurrayItemNode { pub kind: u8, pub name: *const u8, pub name_len: usize, pub tensor: *mut HurrayTensor, pub member_count: u32, }
Expand description

One node of an item, as a C caller sees it.

A flat tagged struct rather than a union, for the reason HurrayKvValue is one: every binding generator downstream of this header reads a struct correctly and few read a union well.

Every pointer in it borrows from the HurrayItem it came from and is valid until hurray_item_destroy. In particular tensor MUST NOT be passed to hurray_tensor_destroy — the item owns it.

Fields§

§kind: u8§name: *const u8

First byte of the node’s name, or null when it has none.

A file names every tensor, heads and members alike, because each gets its own footer-index entry. A stream names none: the names are not on the wire, so there is nothing to borrow and this is null.

§name_len: usize

Byte length of name; 0 when name is null. UTF-8, not NUL-terminated.

§tensor: *mut HurrayTensor

The node’s tensor handle, borrowed: its descriptor and its buffers.

A composite head is the buffer-less tensor it is on the wire, so this is non-null for every node and its buffer list is empty for a head.

§member_count: u32

How many of the nodes following this one are its direct members. 0 for a tensor.
