rustExample of array of structs in Rust
An array of structs in Rust is a collection of structs stored in a contiguous memory location. Structs are custom data types that allow you to store multiple values of different types in a single variable. An array of structs is declared using the [struct; size]
syntax, where struct
is the struct type and size
is the number of elements in the array.
Example code
struct Point {
x: i32,
y: i32,
}
let points = [Point { x: 0, y: 0 }; 5];
Output example
[
Point { x: 0, y: 0 },
Point { x: 0, y: 0 },
Point { x: 0, y: 0 },
Point { x: 0, y: 0 },
Point { x: 0, y: 0 },
]
Code explanation
struct Point { x: i32, y: i32, }
: This declares a struct type calledPoint
with two fields,x
andy
, both of typei32
.let points = [Point { x: 0, y: 0 }; 5];
: This declares an array ofPoint
structs with 5 elements, each withx
andy
fields set to0
.
