Module project 

Loading a DRE project directory into a resolved, validated project.

Every YAML file in the project is parsed and classified by its shape, not its name. Report config merges by report name from anywhere, then resolves with one precedence rule: Binding > report YAML > folder config (deepest wins) > project defaults > built-in defaults.

Re-exports

pub use crate::plugins::DEPS_DIR;

Structs

Binding

A Report paired with a Set (or the report’s single default Binding): everything a run needs.

ColumnOptions

One entry of a columns: map.

Destination

ForEach

for_each: on an output.

LoadOptions

MetaLayer

An unmerged metadata layer. Consumers own its semantics and can explain its origin.

Output

PluginId

One plugin: its kind and name. Written <kind>/<name> (destination/s3), in messages as well as in dre.lock.

PluginRequirement

A declared plugin package.

PluginUse

A plugin the project uses: a profile’s type: or an output’s format:.

ProfileAt

Where a profile: value is written: its file, line and key, as messages name it.

Project

QueryEntry

QuotingDef

quoting: as written: an unset part inherits (table from source), else isn’t quoted.

Report

ScheduleEntry

SetDef

SourceColumn

SourceDef

A dbt-style source: tables in one schema of one system.

SourceTableDef

Template

TemplateBinding

Timing

A timings.yml entry: a timing any schedule can use by name.

Enums

OrphanRows

for_each.on_orphan_rows.

PluginKind

A plugin’s kind; the same type the protocol uses.

PluginSource

Where a plugin comes from: dependencies.yml’s registry:, github: or local:.

RowErrors

for_each.on_row_error.

Constants

DBT_SOURCE_COLUMN_KEYS

DBT_SOURCE_KEYS

dbt source keys DRE accepts but doesn’t use yet.

DBT_SOURCE_TABLE_KEYS

DEFAULT_MAX_POPULATION_ROWS

The default for_each.max_population_rows.

DEFAULT_ROW_CONCURRENCY

The default for_each.concurrency.

DEFAULT_RUN_QUERY_MAX_ROWS

DESTINATION_KEYS

The keys of a destination entry core reads; every other key is the plugin’s.

FOLDER_CONFIG_KEYS

LOGS_DIR

MACROS_DIR

MESSAGE_FORMAT

The built-in format that renders query results into a short headline.

OUTPUT_SHARED_KEYS

PLUGIN_ENTRY_KEYS

Keys of a plugins: entry written as a map.

PLUGIN_KEYS

PROJECT_FILE

PROJECT_KEYS

QUERY_ENTRY_KEYS

REPORTS_DIR

REPORT_KEYS

SCHEDULE_ENTRY_KEYS

Keys of a schedules.yml entry besides its timing (schedule::SCHEDULE_KEYS).

SET_ENTRY_KEYS

SOURCES_KEY

dbt-style source declarations, in any project YAML file.

SOURCE_COLUMN_KEYS

SOURCE_KEYS

Source keys DRE reads.

SOURCE_TABLE_KEYS

TARGET_DIR

TEMPLATE_BINDING_KEYS

Keys of one output.template.bindings entry.

TEMPLATE_FORMATS

The formats that take output.template.

TIMINGS_FILE

The timings file’s name. Other YAML files of timings are recognised by their shape.

Functions

dotted

find_template

Sheet names in an xlsx template, read without modifying it. Where a template file named in YAML (template:, a message’s file:) is read from: the project root, else templates/.

layer_outputs

Apply one report or Set output: layer over the inherited outputs; returns the problems.

load

Parse and validate the project at root. Returns the resolved project when it could be built at all, plus every diagnostic found along the way.

mentions_each

Whether a template reads each.*.

merge_output

Merge an output layer over base. Changing format drops the lower layers’ format options, since they belong to a different format.

output_label

“output name”, or “output 2” for an unnamed one, as messages name an output.

resolve_template

Resolve an output’s template.file, looked up from the folder of yaml (the report’s file) by the rule in crate::template_file.
