Struct __wt_item 

#[repr(C)]
pub struct __wt_item {
    pub data: *const c_void,
    pub size: usize,
    pub mem: *mut c_void,
    pub memsize: usize,
    pub flags: u32,
}

A raw item of data to be managed, including a pointer to the data and a length.

WT_ITEM structures do not need to be cleared before use.

Fields

data: *const c_void

The memory reference of the data item.

For items returned by a WT_CURSOR, the pointer is only valid until the next operation on that cursor. Applications that need to keep an item across multiple cursor operations must make a copy.

size: usize

The number of bytes in the data item.

The maximum length of a single column stored in a table is not fixed (as it partially depends on the underlying file configuration), but is always a small number of bytes less than 4GB.

mem: *mut c_void

Managed memory chunk (internal use).

memsize: usize

Managed memory size (internal use).

flags: u32
