Struct wasmer_types::TableType

source ·
pub struct TableType {
    pub ty: Type,
    pub minimum: u32,
    pub maximum: Option<u32>,
}
Expand description

A descriptor for a table in a WebAssembly module.

Tables are contiguous chunks of a specific element, typically a funcref or an externref. The most common use for tables is a function table through which call_indirect can invoke other functions.

Fields§

§ty: Type

The type of data stored in elements of the table.

§minimum: u32

The minimum number of elements in the table.

§maximum: Option<u32>

The maximum number of elements in the table.

Implementations§

source§

impl TableType

source

pub fn new(ty: Type, minimum: u32, maximum: Option<u32>) -> Self
