Enum udf::MaxLenOptions

#[non_exhaustive]
#[repr(u32)]
pub enum MaxLenOptions {
    IntDefault = 21,
    RealBase = 13,
    Blob = 65_536,
    MediumBlob = 16_777_216,
}

Helpful constants related to the max_length parameter

These can be helpful when calling UdfCfg::set_max_len()

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.

IntDefault = 21

The default max length for integers is 21

RealBase = 13

The default max length of a real value is 13 plus the result of UdfCfg::get_decimals()

Blob = 65_536

A blob can be up to 65 KiB.

MediumBlob = 16_777_216

A mediumblob can be up to 16 MiB.

Trait Implementations

impl Clone for MaxLenOptions

fn clone(&self) -> MaxLenOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MaxLenOptions

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

Formats the value using the given formatter.

impl PartialEq for MaxLenOptions

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

This method tests for self and other values to be equal, and is used by ==.

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

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