Struct CsvSourceConfig 

pub struct CsvSourceConfig {
    pub source_id: SourceId,
    pub path: PathBuf,
    pub anchor_column: Option<String>,
    pub positive_column: Option<String>,
    pub text_column: Option<String>,
    pub trust: f32,
}

Configuration for a CSV-backed data source.

Two modes are supported:

• Role mode — anchor_column is set (with an optional positive_column). Each row produces an Anchor section from anchor_column and a Context section from positive_column (or the anchor text when positive_column is absent).

• Text mode — only text_column is set. Each row produces both an Anchor and a Context section from the same column (SimCSE-style).

anchor_column and text_column are mutually exclusive.

The CSV file must have a named header row. Columns are always looked up by name, so a header-free file cannot be used with this source.

Fields

source_id: SourceId

Stable source identifier used in records and persistence keys.

path: PathBuf

Path to the CSV file.

anchor_column: Option<String>

Column name for anchor text. Enables role mode when set.

Mutually exclusive with text_column.

positive_column: Option<String>

Column name for positive/context text. Used with anchor_column.

When absent in role mode, the anchor text is reused as the context (identical-positive fallback, suitable for contrastive pre-training).

text_column: Option<String>

Column name for single-text mode.

Mutually exclusive with anchor_column.

trust: f32

Trust/quality score assigned to every record from this source.

Implementations

impl CsvSourceConfig

pub fn new(source_id: impl Into<SourceId>, path: impl Into<PathBuf>) -> Self

Create a config for a CSV source with the given identifier and path.

pub fn with_anchor_column(self, column: impl Into<String>) -> Self

Set the column used as the anchor (enables role mode).

pub fn with_positive_column(self, column: impl Into<String>) -> Self

Set the column used as the positive/context (role mode only).

pub fn with_text_column(self, column: impl Into<String>) -> Self

Set the column used as the single text field (enables text mode).

pub fn with_trust(self, trust: f32) -> Self

Override the default trust score.
