Struct DataprofConfigBuilder 

pub struct DataprofConfigBuilder { /* private fields */ }

Builder for constructing DataprofConfig with a fluent API.

The builder pattern provides:

• Clear, self-documenting configuration
• Type-safe construction
• Validation at build time
• Easy preset configurations

Examples

use dataprof_core::config::{DataprofConfigBuilder, IsoQualityConfig};

// Simple configuration with defaults
let config = DataprofConfigBuilder::new()
    .build()
    .expect("Failed to build config");

// Configuration with custom settings
let config = DataprofConfigBuilder::new()
    .output_format("json")
    .verbosity(2)
    .engine("streaming")
    .build()
    .expect("Failed to build config");

// Strict quality profile for finance/healthcare
let config = DataprofConfigBuilder::new()
    .iso_quality_profile_strict()
    .build()
    .expect("Failed to build config");

Implementations

impl DataprofConfigBuilder

pub fn new() -> Self

Create a new builder with default values.

pub fn output_format(self, format: &str) -> Self

Set the default output format.

Valid formats: “text”, “json”, “csv”, “plain”

pub fn colored(self, enabled: bool) -> Self

Enable or disable colored output.

pub fn verbosity(self, level: u8) -> Self

Set verbosity level (0=quiet, 1=normal, 2=verbose, 3=debug).

pub fn show_progress(self, enabled: bool) -> Self

Enable or disable progress bars.

pub fn quality_enabled(self, enabled: bool) -> Self

Enable or disable quality checking.

When enabled, all quality dimensions are calculated:

• Completeness (null detection)
• Consistency (type consistency, mixed types)
• Uniqueness (duplicate detection, high cardinality)
• Accuracy (outlier detection)
• Timeliness (stale data detection)
• Validity (semantic pattern conformance)
• Precision (effective decimal-scale consistency)

pub fn iso_quality_thresholds(self, thresholds: IsoQualityConfig) -> Self

Set custom quality thresholds and score settings.

pub fn quality_score_weights(self, weights: QualityScoreWeights) -> Self

Set relative weights for the overall quality score.

pub fn iso_quality_profile_strict(self) -> Self

Use strict ISO quality thresholds (finance, healthcare).

Stricter thresholds for high-compliance industries:

• Lower null tolerance (30% vs 50%)
• Higher type consistency requirements (98% vs 95%)
• Stricter duplicate detection (1% vs 5%)
• More recent data requirements (2 years vs 5 years)

pub fn iso_quality_profile_lenient(self) -> Self

Use lenient ISO quality thresholds (exploratory, marketing).

More relaxed thresholds for exploratory data:

• Higher null tolerance (70% vs 50%)
• Lower type consistency requirements (90% vs 95%)
• More lenient duplicate detection (10% vs 5%)
• Older data accepted (10 years vs 5 years)

pub fn engine(self, engine: &str) -> Self

Set the default engine selection.

Valid engines: “auto”, “streaming”, “memory_efficient”, “true_streaming”

pub fn chunk_size(self, size: usize) -> Self

Set default chunk size for streaming operations.

pub fn parallel(self, enabled: bool) -> Self

Enable or disable parallel processing.

pub fn max_concurrent(self, max: usize) -> Self

Set maximum concurrent operations.

pub fn max_memory_mb(self, mb: usize) -> Self

Set maximum memory usage in MB (0 = unlimited).

pub fn auto_streaming_threshold_mb(self, mb: f64) -> Self

Set auto-streaming threshold in MB.

pub fn ci_preset() -> Self

Create a configuration optimized for CI/CD pipelines.

• No colors (for log compatibility)
• No progress bars (cleaner output)
• JSON output format
• Verbose logging

pub fn interactive_preset() -> Self

Create a configuration for interactive terminal use.

• Colors enabled
• Progress bars enabled
• Text output format
• Normal verbosity

pub fn production_quality_preset() -> Self

Create a configuration for production quality checks.

• Strict ISO quality thresholds
• Quality checking enabled
• Memory monitoring enabled
• Conservative memory limits

pub fn build(self) -> Result<DataprofConfig, DataProfilerError>

Build the configuration and validate it.

Returns an error if the configuration is invalid.

pub fn build_unchecked(self) -> DataprofConfig

Build the configuration without validation.

Use this only if you’re certain the configuration is valid and want to skip validation for performance reasons.

Trait Implementations

impl Clone for DataprofConfigBuilder

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for DataprofConfigBuilder

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

Formats the value using the given formatter.

impl Default for DataprofConfigBuilder

fn default() -> Self

Returns the “default value” for a type.
