Enum DisplayFormatType

Source
pub enum DisplayFormatType {
    Default,
    Verbose,
    TreeRender,
}
Expand description

Options for controlling how each ExecutionPlan should format itself

Variants§

§

Default

Default, compact format. Example: FilterExec: c12 < 10.0

This format is designed to provide a detailed textual description of all parts of the plan.

§

Verbose

Verbose, showing all available details.

This form is even more detailed than Self::Default

§

TreeRender

TreeRender, displayed in the tree explain type.

This format is inspired by DuckDB’s explain plans. The information presented should be “user friendly”, and contain only the most relevant information for understanding a plan. It should NOT contain the same level of detail information as the Self::Default format.

In this mode, each line has one of two formats:

  1. A string without a =, which is printed in its own line

  2. A string with a = that is treated as a key=value pair. Everything before the first = is treated as the key, and everything after the first = is treated as the value.

For example, if the output of TreeRender is this:

Parquet
partition_sizes=[1]

It is rendered in the center of a box in the following way:

┌───────────────────────────┐
│       DataSourceExec      │
│    --------------------   │
│    partition_sizes: [1]   │
│          Parquet          │
└───────────────────────────┘
