Struct VsamAttributes 

#[non_exhaustive]
pub struct VsamAttributes {
    pub format: String,
    pub encoding: Option<String>,
    pub compressed: bool,
    pub primary_key: Option<PrimaryKey>,
    pub alternate_keys: Option<Vec<AlternateKey>>,
}

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.

format: String

The record format of the data set.

encoding: Option<String>

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

compressed: 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.

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 VsamAttributes

pub fn format(&self) -> &str

The record format of the data set.

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

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

pub fn compressed(&self) -> 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 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 VsamAttributes

pub fn builder() -> VsamAttributesBuilder

Creates a new builder-style object to manufacture VsamAttributes.

Trait Implementations

impl Clone for VsamAttributes

fn clone(&self) -> VsamAttributes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VsamAttributes

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

Formats the value using the given formatter.

impl PartialEq for VsamAttributes

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