Enum cogl::BufferUpdateHint

#[non_exhaustive]
pub enum BufferUpdateHint {
    Static,
    Dynamic,
    Stream,
    // some variants omitted
}

The update hint on a buffer allows the user to give some detail on how often the buffer data is going to be updated.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Static

the buffer will not change over time

Dynamic

the buffer will change from time to time

Stream

the buffer will be used once or a couple of times
