Struct CapabilityCheckLayer 

#[non_exhaustive]
pub struct CapabilityCheckLayer {}

CapabilityCheckLayer validates optional operation arguments against service capabilities.

Similar to CorrectnessChecker, this layer verifies selected optional arguments for write, copy, and list operations against the capabilities of the underlying service. If an argument is not supported, an error is returned directly.

Notes

There are two main differences between this checker with the CorrectnessChecker:

1. This checker provides additional checks for capabilities like write_with_content_type and list_with_versions, among others. These capabilities do not affect data integrity, even if the underlying storage services do not support them.

2. OpenDAL doesn’t apply this checker by default. Users can enable this layer if they want to enforce stricter requirements.

Examples

let _ = Operator::new(services::Memory::default())?
    .layer(CapabilityCheckLayer::new());
