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.

• static: keyword used to declare a static variable
• MY_VARIABLE: name of the variable
• i32: type of the variable
• 10: value of the variable
