Enum Mode 

#[non_exhaustive]
pub enum Mode {
    Read,
    Write,
}

Choose how opened files can be accessed.

Pass a Mode value to GsdFile::open.

In the Mode::Read mode, you can call methods that read the file, such as GsdFile::find_chunk and GsdFile::iter_scalars. Calling methods that write the file, such as GsdFile::write_scalars or GsdFile::sync_all will result in an error.

In the Mode::Write mode, you can call both read and write methods.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Read

Read-only.

Write

Allow both read and write operations.

Trait Implementations

impl Clone for Mode

fn clone(&self) -> Mode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Mode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Mode

fn eq(&self, other: &Mode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
