[−][src]Enum monotron_api::OpenMode
The ways in which we can open a file.
TODO: Replace all these booleans with a u8 flag-set
Variants
ReadOnly
Open file in read-only mode. No writes allowed. One file can be opened in read-only mode multiple times.
Fields of ReadOnly
WriteOnly
Open a file for writing, but not reading.
Fields of WriteOnly
append: bool
If true, the write pointer will default to the end of the file
create: bool
If true, the file will be created if it doesn't exist. If false, the file must exist. See also the exclusive
flag.
exclusive: bool
If true AND the create flag is true, the open will fail if the file already exists.
truncate: bool
If true, the file contents will be deleted on open, giving a zero byte file.
non_blocking: bool
Set to true if read/write requests on this handle should be non-blocking
ReadWrite
Open a file for reading and writing.
Fields of ReadWrite
append: bool
If true, the write pointer will default to the end of the file
create: bool
If true, the file will be created if it doesn't exist. If false, the file must exist. See also the exclusive
flag.
exclusive: bool
If true AND the create flag is true, the open will fail if the file already exists.
truncate: bool
If true, the file contents will be deleted on open, giving a zero byte file.
non_blocking: bool
Set to true if read/write requests on this handle should be non-blocking
