Struct OdbcBufferSettings 

pub struct OdbcBufferSettings {
    pub batch_size: usize,
    pub max_column_size: Option<usize>,
}

Fetch-buffer settings used by the ODBC driver.

max_column_size = Some(_) enables buffered fetching and can truncate long text or binary fields to the configured size. max_column_size = None keeps fetching unbuffered so variable sized values are not truncated by this crate’s buffer allocation.

Fields

batch_size: usize

Number of rows fetched in each batch.

max_column_size: Option<usize>

Maximum text or binary column size in buffered mode, or None for unbuffered mode.

Trait Implementations

impl Clone for OdbcBufferSettings

fn clone(&self) -> OdbcBufferSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OdbcBufferSettings

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

Formats the value using the given formatter.

impl Default for OdbcBufferSettings

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for OdbcBufferSettings

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