#1349 in Rust patterns
4KB
field-visibility
Attribute to specify the visibility of all fields in a Rust struct
.
Usage
Examples
The argument is the visibility mode (i.e. pub
or pub(crate)
).
To set all fields in the struct
to public:
use field_visibility::visibility;
#[visibility(pub)] // Or `pub(crate)`, etc.
struct Widget {
a: i32,
b: i32,
}
This expands to:
use field_visibility::visibility;
#[visibility(pub)]
struct Widget {
pub a: i32,
pub b: i32,
}
When using this attribute, the visibility of individual fields can be set.
use field_visibility::visibility;
#[visibility(pub)]
struct SomeStruct {
field1: i32,
field2: i32,
pub(crate) crate_field: i32,
pub(self) private_field: i32, // Equivalent to private
}
The expansion of this is:
struct SomeStruct {
pub field1: i32,
pub field1: i32,
pub(crate) crate_field: i32,
pub(self) private_field: i32,
}
