Struct DirEntry 

pub struct DirEntry { /* private fields */ }

Implementations

impl DirEntry

pub fn builder() -> DirEntryBuilder<((), (), (), ())>

Create a builder for building DirEntry. On the builder, call .name(...), .inode(...), .typ(...), .offset(...) to set the values of the fields. Finally, call .build() to create the instance of DirEntry.
