Struct RelAttr 

pub struct RelAttr<A = i32> {
    pub size: Range<A>,
    pub binary: Vec<BinaryAttr>,
    pub representation: Option<String>,
}

Fields

size: Range<A>

binary: Vec<BinaryAttr>

representation: Option<String>

Optional user-facing representation preference (short name), e.g. "packed".

Written in Essence as relation (representation packed, …). When present, representation selection heuristics default to this representation if it is applicable.

Implementations

Set the representation preference (Essence short name), returning the updated attributes.

impl RelAttr<IntVal>

pub fn resolve(&self) -> Result<RelAttr, DomainOpError>

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
