verdict-cli-0.1.3 is not a library.

verdict-cli

CLI tool for validating CSV files against a JSON schema.

Installation

Download a pre-built binary from the GitHub releases page, or build from source:

cargo install verdict-cli

Usage

verdict-cli data.csv schema.json

Exit code 0 — all rules pass. Exit code 1 — at least one rule fails.

Flags

Flag	Default	Description
`--format`	`json`	Output format: `json` or `text`
`--max-failed-samples`	`100`	Max failed row samples per rule

Schema format

{
  "columns": [
    { "name": "user_id", "dtype": "int", "constraints": [
      { "constraint": "not_null", "value": true },
      { "constraint": "unique",   "value": true }
    ]},
    { "name": "score", "dtype": "float", "constraints": [
      { "constraint": "between", "value": [0, 100] }
    ]},
    { "name": "country", "dtype": "str" }
  ]
}

Supported dtypes: int, float, str, bool.

Columns without constraints are still declared in the schema — they're loaded and type-checked but not validated against any rules.

Output

Text:

Validation Report: FAILED (2/3 rules passed)
  FAIL: column 'age' — gt(18) — 5 values failed
    row 3: 15
    row 7: 12

JSON:

{
  "passed": false,
  "total_rules": 3,
  "passed_count": 2,
  "failed_count": 1,
  "results": [...]
}

CI usage
