Struct aws_sdk_m2::types::VsamDetailAttributes

#[non_exhaustive]
pub struct VsamDetailAttributes {
    pub encoding: Option<String>,
    pub record_format: Option<String>,
    pub compressed: Option<bool>,

    pub primary_key: Option<PrimaryKey>,

}

The attributes of a VSAM type data set.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

encoding: Option<String>

The character set used by the data set. Can be ASCII, EBCDIC, or unknown.

record_format: Option<String>

The record format of the data set.

compressed: Option<bool>

Indicates whether indexes for this dataset are stored as compressed values. If you have a large data set (typically > 100 Mb), consider setting this flag to True.

cache_at_startup: Option<bool>

If set to True, enforces loading the data set into cache before it’s used by the application.

primary_key: Option<PrimaryKey>

The primary key of the data set.

alternate_keys: Option<Vec<AlternateKey>>

The alternate key definitions, if any. A legacy dataset might not have any alternate key defined, but if those alternate keys definitions exist, provide them as some applications will make use of them.

Implementations

impl VsamDetailAttributes

pub fn encoding(&self) -> Option<&str>

The character set used by the data set. Can be ASCII, EBCDIC, or unknown.

pub fn record_format(&self) -> Option<&str>

The record format of the data set.

pub fn compressed(&self) -> Option<bool>

Indicates whether indexes for this dataset are stored as compressed values. If you have a large data set (typically > 100 Mb), consider setting this flag to True.

pub fn cache_at_startup(&self) -> Option<bool>

If set to True, enforces loading the data set into cache before it’s used by the application.

pub fn primary_key(&self) -> Option<&PrimaryKey>

The primary key of the data set.

pub fn alternate_keys(&self) -> &[AlternateKey]

The alternate key definitions, if any. A legacy dataset might not have any alternate key defined, but if those alternate keys definitions exist, provide them as some applications will make use of them.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .alternate_keys.is_none().

impl VsamDetailAttributes

pub fn builder() -> VsamDetailAttributesBuilder

Creates a new builder-style object to manufacture VsamDetailAttributes.

Trait Implementations

impl Clone for VsamDetailAttributes

fn clone(&self) -> VsamDetailAttributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VsamDetailAttributes

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

Formats the value using the given formatter.

impl PartialEq for VsamDetailAttributes

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