Enum FileFlag 

#[non_exhaustive]
pub enum FileFlag {
    Read,
    Write,
    Create,
    CreateNew,
    Append,
}

A file-open mode flag, mirroring duckdb_file_flag.

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

Open for reading.

Write

Open for writing.

Create

Create the file if it does not exist.

CreateNew

Create the file, failing if it already exists.

Append

Open in append mode.

fn eq(&self, other: &FileFlag) -> 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.
