Methods

impl FieldAccess

pub fn from_access_flags(
    access_flags: u16
) -> Result<HashSet<FieldAccess>, String>

Extracts the list of field access flags that are embedded in the given access flag value.

Returns an error message if the extracted combination of access flags are inconsistent. (This validation has not yet been implemented)

See Table 4.5-A of the JVM specification for more details.

https://docs.oracle.com/javase/specs/jvms/se11/html/jvms-4.html#jvms-4.5-200-A.1

let access_flags = 0b0000_0000_0100_0001;

let mut expected = HashSet::new();
expected.insert(FieldAccess::Public);
expected.insert(FieldAccess::Volatile);

assert_eq!(Ok(expected), FieldAccess::from_access_flags(access_flags));
