rustHow do I declare a variable outside a function in Rust?
Variables declared outside a function in Rust are called static variables
. They are declared using the static
keyword followed by the type of the variable and the name of the variable.
static VARIABLE_NAME: TYPE = VALUE;
For example,
static MY_VARIABLE: i32 = 10;
This declares a static variable MY_VARIABLE
of type i32
with the value 10
.

: keyword used to declare a static variableMY_VARIABLE
: name of the variablei32
: type of the variable10
: value of the variable
