Struct move_binary_format::compatibility::Compatibility

pub struct Compatibility {
    pub struct_and_function_linking: bool,
    pub struct_layout: bool,
}

The result of a linking and layout compatibility check. Here is what the different combinations mean: { struct: true, struct_layout: true }: fully backward compatible { struct_and_function_linking: true, struct_layout: false }: Dependent modules that reference functions or types in this module may not link. However, fixing, recompiling, and redeploying all dependent modules will work–no data migration needed. { type_and_function_linking: true, struct_layout: false }: Attempting to read structs published by this module will now fail at runtime. However, dependent modules will continue to link. Requires data migration, but no changes to dependent modules. { type_and_function_linking: false, struct_layout: false }: Everything is broken. Need both a data migration and changes to dependent modules.

Fields

struct_and_function_linking: bool

If false, dependent modules that reference functions or structs in this module may not link

struct_layout: bool

If false, attempting to read structs previously published by this module will fail at runtime

Implementations

impl Compatibility

pub fn is_fully_compatible(&self) -> bool

Return true if the two module s compared in the compatiblity check are both linking and layout compatible.

pub fn check(old_module: &Module, new_module: &Module) -> Compatibility

Return compatibility assessment for new_module relative to old module old_module.
