Enum Access 

pub enum Access {
    ReadOnly,
    WriteOnly,
    ReadWrite,
}

What a target can do with its data, stated by the target. A target has data to address, so there is no value for neither: a handle that can do neither is not a target (NoData is not HasData).

Variants

ReadOnly

It can be read and not written.

WriteOnly

It can be written and not read.

ReadWrite

It can be read and written.

Implementations

impl Access

pub const fn can_read(self) -> bool

Whether the data can be read.

pub const fn can_write(self) -> bool

Whether the data can be written.

pub const fn covers(self, other: Access) -> bool

Whether everything other can do, this can: what a target must be able to do for a key that declares other to be registered under it.
