Enum Mode

pub enum Mode {
    Standard,
    Cockroach,
}

Specifies the dialect of a sqllogictest file. Different sqllogictest runners have slightly different behavior.

Variants

Standard

In Standard mode, expected query output is formatted so that every value is always on its own line, like so:

query II SELECT * FROM VALUES (1, 2), (3, 4)

1 2 3 4

Row boundaries are not visually represented, but they can be inferred because the number of columns per row is specified by the query directive.

Cockroach

In Cockroach mode, expected query output is formatted so that rows can contain multiple whitespace-separated columns:

query II SELECT * FROM VALUES (1, 2), (3, 4)

1 2 3 4

This formatting, while easier to parse visually, is thoroughly frustrating when column values contain whitespace, e.g., strings like “one two”, as there is no way to know where the column boundaries are. We jump through some hoops to make this work. You might want to refer to this upstream Cockroach commit 0 for additional details.

Trait Implementations

impl Clone for Mode

fn clone(&self) -> Mode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mode

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

Formats the value using the given formatter.

impl PartialEq for Mode

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Mode

impl Eq for Mode

impl StructuralPartialEq for Mode
